characterized in terms of GC, MS, and NMR data. The sensory properties of the odorants, such as odor quality and odor detection threshold value, were determined with a trained panel. Structure-activity relationships are discussed, suggesting that the 1,3-oxygen-sulfur functionality, required for the "olfactophore" of tropical/vegetable notes, can further be extended to the acetylthio derivatives.
通过在碱性条件下将硫代乙酸迈克尔加成到α,β-不饱和2-烷基取代的醛上,采用平行合成的方法制备一系列3-(乙酰硫基)-2-烷基链烷醛,这些醛是通过相应的醛醇缩合反应制得的伯醛为原料。根据GC,MS和NMR数据对目标化合物进行了表征。由训练有素的小组来确定气味的感官特性,例如气味质量和气味检测阈值。讨论了结构-活性关系,表明热带/植物味的“嗅觉基团”所需的1,3-氧-硫官能度可进一步扩展至乙酰硫基衍生物。
