以天然易得的L-脯氨酸为原料,经N-酰化,Baylis-Hillman反应,不对称氢化,巯基化等四步反应,高效地开发了一条不对称合成卡托普利的新方法,其化学结构通过IR和1H NMR进行了表征.
A new and efficient asymmetric synthesis of active pharmaceutical ingredients(API) named Captopril,was described,and Captopril was achieved by N-acylation,Baylis-Hillman reaction,asymmetric hydrogenation and thiolation in high optical purity from nature L-proline.The chemical structure of Captopril was confirmed by IR and 1H NMR.
