Description

[Technical field]

[0001] The present invention relates to compounds of formula (I) for use as aroma chemicals to impart a sweet, tonka, acacia, woody, etc. impression to a composition. The present invention further relates to the use of compounds of formula (I) as aroma chemicals to impart a sweet, tonka, acacia, and / or woody, etc. impression to a composition, and also to enhance and / or modify the aroma of a composition. The present invention is further directed to compositions comprising at least one compound of formula (I) and (i) at least one aroma chemical different from the compound of formula (I), or (ii) at least one non-aroma chemical carrier, or (iii) both (i) and (ii). [Background technology]

[0002] Fragrance chemicals, and in particular fragrances, are of great interest, especially in the fields of cosmetics, cleaning and laundry compositions.

[0003] Although a large number of synthetic aroma chemicals already exist, new ingredients are always needed to be able to meet the many properties desired in a wide variety of application fields.These include, firstly, sensory properties, i.e., the compound must have advantageous olfactory properties.Furthermore, aroma chemicals must also have additional positive secondary properties, such as, for example, efficient preparation methods, the possibility of providing a better sensory profile as a result of synergistic effects with other aroma chemicals, higher stability under certain application conditions, better and longer persistence, etc.

[0004] Such properties are of particular interest in compositions such as, for example, care compositions, hygiene products, cleaning compositions, fabric detergent compositions, and compositions for scent dispensers.

[0005] Of particular interest are aroma chemicals that can provide one or more distinct sensory impressions to the composition, thereby contributing to a rich and interesting sensory profile, especially the olfactory profile of the composition.In this context, aroma chemicals that can provide sweet, tonka, acacia, and / or woody impressions are of great interest.In addition, persistence and tenacity are of particular interest in order to obtain a long-lasting odor impression in the composition and on the surface treated with the composition.

[0006] However, the search for substances with specific and well-defined sensory properties, such as a specific odor, is very difficult, since even small changes in chemical structure can lead to large changes in sensory properties, such as odor and / or flavor. Thus, the search for new aroma chemicals is a difficult and arduous task, in most cases, without knowing whether a substance with the desired odor and / or flavor will actually be found.

[0007] The object of the presently claimed invention is to provide substances which can be used as aroma chemicals, either alone or in mixtures in compositions, and in particular there is a need for strong odorous substances which have a pleasant odor. Furthermore, they should be capable of being combined with other aroma chemicals, allowing the creation of new and advantageous sensory profiles, which can be used in compositions. Summary of the Invention [Problem to be solved by the invention]

[0008] It is an object of the present invention to provide novel aroma chemicals having a pleasant olfactory impression; preferably a combination of two or more of the impressions selected from the group consisting of sweet notes, tonka notes, acacia notes, and woody notes.

[0009] It is a further object of the present invention that the fragrance chemicals should be available from readily available starting materials, allowing for their rapid and economical production. [Means for solving the problem]

[0010] These objects have been achieved by providing compounds of formula (I) according to the present invention.

[0011] Surprisingly, it has been found that the compounds of formula (I) according to the invention have a pleasant olfactory impression; preferably a combination of two or more of the impressions selected from sweet notes, tonka notes, acacia notes and woody notes.

[0012] A first aspect of the currently claimed invention relates to a compound of formula (I) for imparting a fragrance impression to a composition. [ka] or a stereoisomer thereof.

[0013] A second aspect of the presently claimed invention is a compound represented by formula I(a) and I(b): [ka] The present invention relates to compounds of formula (I) including a mixed composition of enantiomers represented by the compound:

[0014] A third aspect of the currently claimed invention relates to a method of imparting a fragrance impression to a composition comprising the step of adding to the composition at least one compound of formula (I).

[0015] Another aspect of the presently claimed invention relates to the use of at least one compound of formula (I) for modifying a composition's fragrance characteristics.

[0016] A further aspect of the currently claimed invention relates to a method for enhancing the aroma of a composition, said method comprising the step of mixing at least one compound of formula (I) with other ingredients, such as at least one other aroma chemical different from the compound of formula (I) and / or at least one non-aroma chemical carrier, to obtain an aroma chemical composition.

[0017] Yet another aspect of the presently claimed invention relates to a method for modifying the aroma of a chemical composition, said method comprising the step of incorporating at least one compound of the presently claimed invention into the aroma chemical composition to obtain an aroma-modified aroma chemical composition.

[0018] Furthermore, the compounds of formula (I) can be produced in good yield and purity by simple synthesis starting from readily available starting materials. Thus, the compounds of the presently claimed invention can be produced in a facile, cost-effective manner on a large scale. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] The following detailed description is exemplary in nature and is not intended to limit the presently claimed invention or the application and uses of the presently claimed invention. Moreover, there is no intention to be bound by any theory presented in the preceding technical field, background, brief summary, or the following detailed description.

[0020] As used herein, the terms "comprising," "comprises," and "comprised of" are synonymous with "including," "includes," or "containing," "contains," and are inclusive or open-ended and do not exclude additional, unrecited members, elements, or method steps. The terms "comprising," "comprises," and "comprised of," as used herein, should be understood to include the terms "consisting of," "consists," and "consists of."

[0021] Furthermore, terms such as "(a)", "(b)", "(c)", "(d)" and the like in the specification and claims are used to distinguish between similar elements and are not necessarily used to describe an order or chronology. It is to be understood that terms so used are interchangeable under appropriate circumstances and that embodiments of the subject matter described herein can operate in orders other than those described or illustrated herein. For the sake of convenience, terms such as "(A)", "(B)" and "(C)" or AA), BB) and CC) or "(a)", "(b)", "(c)", "(d)", "(i)", "(ii)" and the like, when referring to steps of a method or use or assay, are not consistent in time or time interval between the steps, i.e., the steps can be performed simultaneously, or there can be a time interval of seconds, minutes, hours, days, weeks, months, or even years between such steps, unless otherwise indicated in the application, as described herein above or below.

[0022] In the following passages, various aspects of the subject matter are defined in more detail. Each aspect so defined can be combined with any other aspect, unless expressly indicated to the contrary. In particular, any feature indicated as being preferred or advantageous can be combined with any other feature indicated as being preferred or advantageous.

[0023] References throughout this specification to "one embodiment" or "an embodiment" or "preferred embodiment" mean that a particular feature, structure, or characteristic described in connection with that embodiment is included in at least one embodiment of the presently claimed invention. Thus, the appearance of the phrases "in one embodiment" or "in a preferred embodiment" or "in a preferred embodiment" in various places throughout this specification may, but do not necessarily, all refer to the same embodiment. Furthermore, as will be apparent to one of ordinary skill in the art from this disclosure, features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. Furthermore, as will be appreciated by one of ordinary skill in the art, some embodiments described herein include some features but do not include other features included in other embodiments, and combinations of features of different embodiments are meant to form different embodiments within the scope of the subject matter. For example, in the appended claims, any of the claimed embodiments may be used in any combination.

[0024] Furthermore, ranges defined throughout this specification are inclusive of the end values, i.e., a range of 1 to 10 is intended to include both 1 and 10. For the avoidance of doubt, the applicant reserves the right to any equivalents available under applicable law.

[0025] In the context of the present invention, the term "aroma" refers to sensory properties and includes smell and / or flavor.

[0026] The term "aroma chemical" refers to a substance used to obtain a sensory or organoleptic (used interchangeably herein) impression, including its use to obtain an olfactory and / or flavor impression. The term "olfactory impression" or "note" (used interchangeably herein) refers to an odor impression without a positive or negative judgement, and as used herein, the term "scent impression" or "fragrance impression" or "aroma impression" (used interchangeably herein) relates to an odor impression that is generally perceived as pleasant. Thus, "fragrance" or "aroma" refers to an aroma chemical that primarily induces a pleasant odor impression. Flavor refers to an aroma chemical that induces a taste impression.

[0027] As used herein, the term "aroma composition" refers to a composition that induces an aroma. The term aroma composition includes "odor composition" and / or "flavor composition." An odor composition is a composition that induces primarily an odor impression, and a flavor composition is a composition that induces primarily a taste impression.

[0028] The term "aroma profile" means the overall aroma impression of an aroma chemical, which is made up of the individual aroma impressions of the aroma chemicals.

[0029] The term olfactory composition includes "fragrance compositions" or "fragrance compositions" (used interchangeably herein) that primarily induce an olfactory impression that is generally perceived as pleasant.

[0030] The general expression "advantageous sensory properties" or "advantageous sensory properties" refers to the pleasantness and conciseness of the sensory impression conveyed by the aroma chemicals. "Pleasantness" and "clarity" are terms well known to those skilled in the art, such as perfumers. Pleasantness generally refers to a spontaneously generated and positively perceived pleasant sensory impression. However, "pleasant" does not necessarily have to be synonymous with "sweet". "Pleasant" can also be a musk or sandalwood smell. "Clarity" generally refers to a spontaneously generated sensory impression that produces a reproducible and identical reminiscence of something specific in the same test panelist. For example, if a substance has an odor that spontaneously reminds of the odor of "apple", then the odor will be distinctly "apple". If this apple odor is very pleasant, for example because it reminds of sweet and ripe apples, then the odor is called "pleasant". However, a typically sour apple odor can also be distinct. If smelling the substance elicits both responses, in this example resulting in a pleasant, distinct apple odor, then the substance has particularly advantageous sensory properties.

[0031] As used herein with reference to a composition, method or use of two compounds, the phrases "combination," "in combination with," or "combined with" take into account that the two compounds need not be used in the form of a physical mixture of said compounds, but can be used (e.g., added) separately. When the compounds are used separately, they can be used (e.g., added) sequentially in any order (i.e., one after the other) or in parallel (i.e., essentially simultaneously).

[0032] The terms "boosting" or "boost" are used herein to describe the effect of enhancing and / or modifying the fragrance of a fragrance chemical or composition. The term "enhancing" includes improving the pleasantness and / or clarity of the fragrance, and / or improving the intensity. The term "modifying" includes changing the fragrance profile. The terms "pleasantness" and "clarity" are well known to those skilled in the art, such as perfumers, and have their respective meanings.

[0033] Intensity can be determined by determining the threshold. Although not necessary to define any further, the odor threshold is the concentration of a substance in the relevant gas space at which a representative test panelist can still perceive an odor impression.

[0034] The enhancer effect is particularly desired in fragrance compositions where applications require a top note-characterized odor that is delivered particularly quickly and intensively, such as in the taste area in deodorants, deodorants or chewing gum.

[0035] The terms "the present invention relates to" and "the present invention is directed to" are used interchangeably throughout the present invention.

[0036] The term "stickiness" refers to the evaporation behavior of a fragrance chemical over time. Stickiness can be determined, for example, by applying the fragrance chemical to a test strip and then olfactory evaluating the odor impression of the test strip. For fragrance chemicals with high stickiness, the time interval before panelists can still discern the fragrance impression is longer.

[0037] The term "persistence" refers in particular to the interaction of fragrance chemicals with a surface, e.g., skin or a fabric, after subsequent treatment of the surface, e.g., washing. Persistence can be determined, for example, by washing a fabric with a fabric detergent composition comprising the fragrance chemical, followed by an olfactory evaluation of the fabric immediately after washing (wet fabric), and an evaluation of the dried fabric after extended storage.

[0038] The term "stability" describes the behavior of a fragrance chemical when in contact with oxygen, light, and / or other substances. A highly stable fragrance chemical maintains its fragrance profile over time, preferably in a wide variety of compositions and under a variety of storage conditions.

[0039] In order to impart a long-lasting fragrance impression to the composition or to surfaces treated with the composition, the tenacity, persistence and stability of the fragrance chemicals in the composition should preferably be high.

[0040] Unless otherwise indicated herein, "compound (I)" as described herein refers to a compound defined by formula (I) or a stereoisomer thereof.

[0041] The term "stereoisomer" is a general term described by IUPAC and is used for all isomers of individual compounds that differ only in the orientation of the atoms in space, and not in the connectivity of the atoms. The term stereoisomer therefore includes mirror image isomers (enantiomers), geometric isomers (cis / trans or E / Z) isomers, and diastereoisomers. For the exact definition of the term, see the IUPAC definition or G. Helmchen: "Vocabulary and Nomenclature of Organic Stereochemistry". In Houben-Weyl E21a, Stereoselective Synthesis. Helmchen, RW Offmann, J. Mulzer, E. Schaumann (Hrsg.), 1995, 1-74. The possible isomers may exist as mixtures (i.e. racemates, cis / trans mixtures, or mixtures of diastereoisomers).

[0042] use One embodiment of the presently claimed invention provides a compound of formula (I) for imparting a fragrance impression to a composition. [ka] or a stereoisomer thereof.

[0043] In one embodiment, the compounds of formula Ia and Ib [ka] Compounds of formula (I) including mixed compositions of enantiomers represented by the compounds

[0044] In one embodiment, the compound of formula I(a) and the compound of formula I(b) may be used alone or in any mixture in any ratio.

[0045] In another embodiment, the mixture of the compound of formula I(a) and the compound of formula I(b) is a mixture in which the ratio of the compounds ranges from 1:99 to 99:1.

[0046] In another embodiment, the mixture of the compound of formula I(a) and the compound of formula I(b) is a 50:50 ratio mixture of the compounds.

[0047] A person skilled in the art can adjust the ratio of the compound of formula I(a) and the compound of formula I(b) to reach a specific ratio within the range of 0.1:99.9 to 99.9:0.1 to impart a specific fragrance impression or several fragrance impressions to the composition.
