Squalene–hopenecyclase (SHC) converts squalene (C30) into pentacyclic triterpenes of hopene and hopanol. A linear sesquiterpene, (6E,10E)-2,6,10-trimethyldodeca-2,6,10-triene, underwent cyclizationcatalyzed by SHC, affording the following six bicyclic sesquiterpenes (drimane skeleton) in relatively high yield (68%): drim-7(8)-ene, drim-8(12)-ene, drim-8(9)-ene, driman-8α-ol, driman-8β-ol, and the
Compounds of formula (I), wherein R1 is hydrogen, methyl or ethyl, and R2 is methyl or ethyl, having woody and ambery odor notes, their use as fragrance ingredient and perfumed products comprising them.
