    • 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.
    • 描述的是双环内酯,根据通用结构定义的稠环内酯和根据通用结构定义的螺内酯:用于增强,增强或赋予香料组合物,香料制品,古龙水和加香聚合物中的香气; 制备这种双环内酯的方法及其中间体。在结构中:Z是部分之一:R 1或R 3中的一个是甲基,另一个是氢; 且R 4,R 5,R 6,R 7,R 8和R 9为氢或不相邻的C 1 -C 3烷基。 在结构中:Y表示具有以下结构的C 2 -C 12取代或未取代的亚烷基,亚烯基或链二烯基;并且完成C 5 -C 15环烷基,环链二烯基或环烯基环部分; 并且其中R12,R13,R14,R16,R17,R28,R29,R30和R31表示氢或C1-C3不相邻的烷基; 其中s为0至10的整数; t是0到10的整数; v为1或2的整数; 条件是根据不等式,s和t之和在0和10之间:0 <= s + t <= 10; 0 <= s <= 10; 0 <= t <= 10。
