The compounds according to the general formula
in which formula the dotted lines indicate a single or a double bond, n and m are 0 or 1, R1 is hydrogen or an acyl group -C(O)R3, R3 being a linear or branched alkyl or alkylene group from C1 to C8, the oxygen atom being bound to the adjacent α-carbon atom by a double bond in the case where n is 0 and by a single bond in the case where n is 1, R2 is hydrogen or a linear or branched alkyl, alkenyl or alkoxy group from C1 to C8, or R2 is an alkenoxy group which is linked to the group R1 to form a 1,3-dioxolane cycle having 5 to 7 ring members, are useful perfuming ingredients. The most preferred compounds according to the invention are those which have a damascone- or damascenone-like structure, with the methyl substituent being in 4-position of the ring instead of the 2-position, as is the case in damascones and damascenones.
通式如下的化合物
式中虚线表示单键或双键,n 和 m 为 0 或 1,R1 为氢或酰基-C(O)R3,R3 为 C1 至 C8 直链或支链烷基或亚烷基,在 n 为 0 的情况下,氧原子通过双键与相邻 α 碳原子结合,在 n 为 1 的情况下,通过单键与相邻 α 碳原子结合、R2 是氢或 C1 至 C8 的直链或支链烷基、烯基或烷氧基,或 R2 是烯氧基,与基团 R1 连接形成具有 5 至 7 个环成员的 1,3-二
氧戊环。根据本发明,最优选的化合物是那些具有类似
大马士酮或
大马士酮结构的化合物,其甲基取代基位于环的 4 位,而不是像
大马士酮和
大马士酮那样位于 2 位。
