chiral 催化的 Morita-Baylis-Hillman 醋酸盐的 enantioselective allylic 胺化作用基于环己烷的 thiourea 磷化氢催化剂被调查。面对 20 mol% 导出松香的 thiourea 磷化氢 3j, chiral 胺在多达 88% 产量和多达 85% ee 被获得。
The enantioselective allylic amination of Morita-Baylis-Hillman acetates catalyzed by chiral cyclohexane-based thiourea-phosphine catalysts was investigated. In the presence of 20 mol% rosin-derived thiourea-phosphine 3j, the chiral amines were obtained in up to 88% yield and up to 85% ee.
