Estimating the term…
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 are 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.

A perfumed article comprising a perfumed article base and an aroma augmenting, enhancing or imparting quantity and concentration of a bicyclic lactone having the structure:
A perfumed polymer comprising a microporous polymer and contained in the interstices thereof an aroma augmenting, enhancing or imparting quantity and concentration of a bicyclic lactone having the structure:
A perfume composition comprising a perfume base and intimately admixed therewith an aroma augmenting, enhancing or imparting quantity of a bicyclic lactone having the structure:
A bicyclic lactone having the structure:
A process for the preparation of a bicyclic lactone comprising the steps of carrying out the reaction sequence in order:
A process for augmenting, enhancing or imparting an aroma in or to a consumable material selected from the group consisting of perfume compositions, perfumed articles, colognes and perfume polymers, comprising the step of intimately admixing with a consumable material base an aroma augmenting, enhancing or imparting quantity and concentration of bicyclic lactone having the structure:
