β-alkyl substituted γ-lactones and whiskey lactone analogues were synthesized, and the odor properties were evaluated. During the preparation of the chiral intermediates, we found good reaction conditions for the highly enantioselective esterification of 3-arylmethyl-2-methyl-1-propanols to kinetically resolve them. The results of the olfactory evaluations of the synthesized lactones revealed that the alkyl
合成了具有光学活性的β-烷基取代的γ-内酯和威士忌内酯类似物,并评估了其气味特性。在手性中间体的制备过程中,我们发现了3-芳基甲基-2-甲基-1-丙醇的高度对映选择性酯化反应的良好反应条件,以动力学方式将它们拆分。合成内酯的嗅觉评价结果表明,γ-内酯环上的烷基对气味分布起重要作用。
