Starting from an optically pure alcohol, (R)-(3), which was prepared by enzymatic hydrolysis of the racemic acetate (2) or enantioselective reduction of the ketone derivative (4), the chiral total synthesis of mitragynine (1), a major corynanthe-type indole alkaloid having an analgesic effect in Mitragyna speciosa, was accomplished.
由光学纯的醇(R)-(3)起始,其是通过消旋乙酸外消旋体(2)或对映体选择性还原酮衍生物(4)进行手性全合成的米格炔宁(1)制备的。主要柯楠因型吲哚生物碱具有镇痛作用帽柱木桐,被完成。
