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.
本发明涉及新型化合物及其在香料组合物中的应用。本发明的新型六氢乙烯基色烷和相关的六氢乙烯基色烯化合物由下式表示:其中R1为氢或甲基;R2和R2'相同且为氢或甲基;R3和R3'相同且为氢或甲基;R4和R5独立地为氢或甲基;R6为甲基、乙基或异丙基,但当R1为H时,R2和R3'形成含有1或2个碳原子的烷基桥,其中虚线表示单键或双键。
