The synthesis and sensory evaluation of enantiomeric sets of sedanenolide (1) and 3-butylphthalide (3) are described. The asymmetric synthesis was achieved via the intramolecular Diels-Alder reaction of chiral propargylester (5) which was prepared from optically active propargyl alcohol (4) and 2,4-pentadienoic acid. The sensory evaluation of these enantiomers revealed that there were distinct differences
描述了对苯二酚内酯(1)和3-丁基邻苯二甲酸酯(3)的对映体的合成和感官评价。不对称合成通过手性炔丙基酯(5)的分子内Diels-Alder反应实现,该手性炔丙基酯由旋光的炔丙醇(4)和2,4-戊二烯酸制备。这些对映体的感官评估表明,它们的香气特征和气味阈值之间存在明显差异。
