Cyclic Oxy Ether Compounds for Floral-Green and Watery Notes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing perfumery compounds lack floral-green and watery notes, and there is a need for novel odorants that can enhance or modify perfuming compositions to impart these specific scents.
Innovation Solution
The use of cyclic oxy ether compounds of formula (I), characterized by a carbon-carbon double bond and specific alkyl or alkenyl groups, as perfuming ingredients to impart floral-green and watery notes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing perfumery compounds are used, then perfuming compositions can be formulated, but they lack floral-green and watery notes
Solution Approach 1:
The patent introduces a new chemical parameter - the carbonyl group on the alkylic ether substituent - which fundamentally changes the odor profile of the compound. This structural modification transforms existing ether compounds into compounds with distinct floral-green and watery notes, directly resolving the contradiction by changing molecular parameters to achieve desired sensory properties
Solution Approach 2:
The invention creates a composite molecular structure combining a cyclic ether backbone with a carbonyl-containing alkylic substituent. This composite structure integrates functional groups from different chemical classes (ether and carbonyl) to produce novel organoleptic properties that neither component alone provides, specifically the floral-green and watery notes
2Adaptability or versatility
If novel compounds with floral-green notes are discovered, then perfuming compositions gain enhanced odor properties, but the compounds are not previously known in perfumery
Solution Approach 1:
The patent employs systematic variation of established chemical parameters (carbonyl group position, alkyl chain length, cyclic structure) within known chemical frameworks to generate novel perfumery compounds. This self-service approach allows the inventors to create new odorants using modifications of existing chemical knowledge and structures, rather than relying on complete novel discovery

AI summary
34 Abstract The present invention relates to the use as perfuming ingredients, e.g. to impart odor notes of the floral-green (jasmine like) and watery type, of cyclic oxy ether compounds of formula 5 (I) in the form of any one of its stereoisomers or a mixture thereof, and wherein the dotted line represents a carbon-carbon single or double bond; p represents 0 to 3, preferably 1 to 3; n represents 0 to 2; R represents, independently from each other hydrogen, a C1-C6 alkyl or C2-C6 alkenyl group each optionally substituted by an ester group; R1 represents, 10 independently from each other, a hydrogen atom or a C1-C3 alkyl group.
