The total synthesis of (−)-julocrotine (1) starting from l-glutamic acid in 41% overall yield is described. The methodology utilizes protection, deprotection, and regioselection (carbonyl differentiation via oxazolidinone) protocols, and glutarimide ring formation is the key step.
描述了从1-谷氨酸开始以41%的总产率起始的(-)-julocrotine(1)的总合成。该方法利用保护,脱保护和区域选择(通过恶唑烷酮的羰基区分)方案,而戊二酰亚胺环的形成是关键步骤。
