Natural substances such as pelletierine and its analogues have been prepared in up to 97% ee and good yield by a protective-group-free, biomimetic approach. Usage of benzonitrile or acetonitrile as solvents effectively prevents product racemization.
通过无保护基团的仿生方法,可以以高达97%的ee和良好的收率制备天然物质(例如小丸碱及其类似物)。使用苄腈或乙腈作为溶剂可有效防止产物外消旋。
