structure–odor relationships, we synthesized 13 analogs of compound 1 and evaluated their odors. As a result, it was found that the presence of two double-bonds and branched methyl group at the terminal position in the side chain was essential in order to have a citrus-like odor. Substitution of the side chain with appropriate length at the appropriate 4-position of the 2(5H)-furanone ring was also an important
DAMASCENOLIDE TM [ 1,4-(4-甲基戊-3-烯-1-基)呋喃-2-(5 ħ) -酮],其具有柑橘样气味,是玫瑰一个重要香气成分。我们以前曾报道过1的双键异构体的合成和气味评估,并得出结论,双键的位置和几何异构对气味有显着影响。为了加深对结构-气味关系的了解,我们合成了13种化合物1的类似物并评估他们的气味。结果发现,在侧链的末端位置存在两个双键和支链甲基对于具有柑橘类气味是必不可少的。在2(5 H)-呋喃酮环的适当4位取代适当长度的侧链也是决定气味质量的重要因素。
