摘要:
The present invention concerns some derivatives of the 2-ethyl-4-(2',2'-dimethyl- 3-alkyl-3'-cyclopenten-1'-yl)-4-penten-1-ol type, as defined in the description. Said compounds are very interesting perfuming ingredients due to their unusual combination 5 of sandalwood and floral notes. The present invention concerns the use of said compounds in the perfumery industry as well as the compositions or articles containing said compounds.
摘要:
The present invention relates to some perfuming ingredients which are esters of formula (I) wherein R 1 and R 2 represent each a hydrogen atom or a methyl or ethyl group; and R 3 represents a C 5 -C 8 group of formula satured or unsatured linear, branched or cyclic group.
摘要:
The present invention concerns some nitrile derivatives of formula (I) wherein R represents a methyl or ethyl group; R 6 represents a hydrogen atom or a methyl or ethyl group; R 1 and R 2 , taken separately, represent each a hydrogen atom or a OR 7 group, R 7 being a hydrogen atom or a C 1-2 alkyl or acyl group; or said R 1 and R 2 , taken together, represent an oxygen atom, a CH 2 group or a carbon-carbon double bond; and - R 3 , R 4 and R 5 are each a hydrogen atom; or - a) R 5 is a hydrogen atom and R 3 and R 4 , taken together, represent an oxygen atom, a CH 2 group or a carbon-carbon double bond; or - b) R 4 is a hydrogen atom and R 3 and R 5 , taken together, represent an oxygen atom, a CH 2 group or a carbon-carbon double bond; which are very useful as perfuming ingredients to confer lemon type odor notes.
