The present invention refers to the use as flavor or fragrance of a compound of formula (I)
wherein
R4 is hydrogen and the bond between C-3 and C-4 is a single bond or the dotted line together with the bond between C-3 and C-4 represents a double bond; or
R4 is methylene, forming with C-3 and C-4 a cyclopropane ring;
R3 is hydrogen, C1, C2, C3, C4, C5, C6 alkyl, or C2, C3, C4, C5, C6 alkenyl; and
I) R1 and R2 together with the carbon atom to which they are attached form a carbonyl group; or
II) R1 is hydroxyl and R2 is selected from C1, C2, C3 alkyl, and C2, C3, C4 alkenyl.
本发明涉及使用式(I)化合物作为
香料或香精,其中:R4为氢,C-3和C-4之间的
化学键是单键或点状线与C-3和C-4之间的
化学键一起表示双键;或者R4为亚甲基,与C-3和C-4形成
环丙烷环;R3为氢、C1、C2、C3、C4、C5、C6烷基或C2、C3、C4、C5、C6烯基;且(I) R1和R2与它们附着的碳原子一起形成羰基;或者(II) R1为羟基,R2选择自C1、C2、C3烷基和C2、C3、C4烯基。
