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 &agr;-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.
根据通用公式中的化合物,其中点线表示单键或双键,n和m为0或1,R1为氢或酰基—C(O)R3,R3为C1至C8的直链或支链烷基或烷基烯基基团,氧原子通过双键与相邻的α-碳原子结合(当n为0时),或通过单键结合(当n为1时),R2为氢或来自C1至C8的直链或支链烷基、烯基或烷氧基团,或者R2是与基团R1连接形成具有5至7个环成员的1,3-二氧杂环戊烷环的烯氧基基团,这些化合物是有用的香料成分。根据本发明最优选的化合物是那些具有达马松酮或达马瑟酮类似结构的化合物,其中甲基取代基位于环的4位而不是达马松酮和达马瑟酮中的2位。
