Abstract
Described are bicyclic lactones, both fused ring lactones defined according to the generic structure:and spiro lactones defined according to the generic structure:uses thereof in augmenting, enhancing or imparting aromas in or to perfume compositions, perfumed articles, colognes and perfumed polymers; processes for preparing such bicyclic lactones and intermediates therefor.In the structure:Z is one of the moieties:one of R1 or R3 is methyl and the other is hydrogen; and R4, R5, R6, R7, R8 and R9 hydrogen or nonadjacent C1–C3 alkyl. In the structure:Y represents C2–C12 substituted or unsubstituted alkylidenyl, alkenylidenyl or alkadienylidenyl having the structure:and completes a C5–C15 cycloalkyl, cycloalkadienyl or cycloalkenyl ring moiety; and wherein R12, R13, R14, R16, R17, R28, R29, R30 and R31 represent hydrogen or C1–C3 nonadjacent alkyl; wherein s is an integer of from 0 up to 10; t is an integer of from 0 up to 10; and v is an integer of 1 or 2; with the proviso that the sum of s and t is between 0 and 10 according to the inequalities: 0≦s+t≦10; 0≦S≦10; and 0≦t≦10.
