Esters and ethers of 2,2,4,4-tetramethylcyclobutane-1,3-diol for use as aroma chemicals

Abstract

The present invention relates to the use of a compound of the general formula (I) wherein R1 is C1-C4-alkyl or -(C=O)-R3, R2 is hydrogen, C1-C4-alkyl or -(C=O)-R4, and R3 and R4, independently of oneanother, are selected from the group consisting of hydrogen and C1-C4-alkyl, a stereoisomer thereof or a mixture of stereoisomers thereof, as an aroma chemical, to aroma chemical compositions comprising at least one compound of the general formula (I), a stereoisomer thereof or a mixture of stereoisomers thereof, and to a method for preparing a fragranced ready-to-use composition, which comprisesincorporating at least one compound of the general formula (I), a stereoisomer thereof or a mixture of stereoisomers thereof, into a ready-to-use composition. The present invention further relates tospecific ethers and specific esters of the compounds of the general formula (I) and a method for their preparation.

Description

[0001] The present invention relates to the use of esters and ethers of 2,2,4,4-tetramethylcyclobutane-1,3-diol as aroma chemicals, comprising at least one 2,2,4,4-tetramethyl Fragrance chemical compositions of esters or ethers of cyclobutane-1,3-diols, and processes for preparing perfuming ready-to-use compositions comprising incorporating at least one 2,2,4,4-tetramethylcyclo The esters or ethers of butane-1,3-diol are incorporated into ready-to-use compositions. The invention further relates to specific ethers and specific esters of 2,2,4,4-tetramethylcyclobutane-1,3-diol and processes for their preparation. [0002] Background of the invention [0003] Fragrance chemicals, especially fragrances, are of great importance especially in the field of cosmetics and cleaning and laundry compositions. Fragrances of natural origin are mostly expensive, are generally limited in their availability, and are also subject to variations in their content, purity, etc. due to fluctuations ...
