Abstract:
The present invention relates to novel compounds and their use in fragrance compositions. Novel hexahydro ethanochromene and related hexahydro ethanochromane compounds of the present invention are represented by formula: wherein R1 is hydrogen or methyl; R2 and R2′ are identical and are hydrogen or methyl; R3 and R3′ are identical and are hydrogen or methyl; R4 and R5 are independently hydrogen or methyl; R6 is methyl, ethyl, or isopropyl, with the proviso that when R1 is H, R2 and R3′ form an alkylene bridge containing 1 or 2 carbon atoms, and wherein the broken line represents a single or double bond.
