Cyclopentylalkyl-nitriles

Abstract

The present invention provides compounds of formula I wherein R1 and R3 are independently H or C1-3 alkyl, and R2 is H, C1-3 alkyl, methylene or ethylidene, with the proviso that R1 and R2 are not simultaneously H; n is 0 or 1; and is a single or a double bond, wherein a maximum of two double bonds are present in the compound. Compounds of formula II are also provided: wherein A is selected from the group of CR4R5OH, CR4R5OC(O)R6, CO2R6, CN and C(O)R4; R1, R3, R4, and R5 are independently H or C1-3-allyl; R2 is H, C1-3-alkyl, methylene, or ethylidene; R6 is H, C1-3 alkyl, C2-4 alkenyl, or alkinyl; n is 0 or 1; and is a single or a double bond, wherein a maximum of two double bonds are present. Compositions containing compounds of formulae I and II, as well as methods for imparting fragrance to substrates using such compounds are also provided.
