Abstract The regio-and diastereoselectivity of reactions of selected α-(1-hydroxyalkyl)acrylate derivatives with sodium methanethiolate have been investigated. The hydroxy compounds typically undergo conjugate addition with up to 66% d.e., while the acetoxy and bromo analogues favour SN' and SN reactions, respectively.
摘要 研究了选定的 α-(1-羟烷基)丙烯酸酯衍生物与甲硫醇钠反应的区域选择性和非对映选择性。羟基化合物通常以高达 66% 的 de 进行共轭加成,而乙酰氧基和溴类似物分别有利于 SN' 和 SN 反应。
