报道了一种在室温条件下和在四氢呋喃水溶液中用Zn/HCO2NH4还原4β-叠氮鬼臼毒素制备抗癌药物中间体4β-氨基鬼臼毒素的新方法. 此方法具有产率高(96%)、不需要用贵金属(如钯或钐)催化和无水条件、操作方便等优点. 最佳的反应条件为: 底物、Zn和HCO2NH4的物质的量之比为1∶2∶4, 反应溶剂为85%四氢呋喃水溶液, 反应时间为5 h.

4β-Aminopodophyllotoxin, a very important intermediate of anticancer drugs, has been successfully synthesized from 4β-azidopodophyllotoxin in a 96% yield by reduction with Zn/HCO2NH4 in 85% aq. tetrahydrofuran for 5 h. Compared to the reported results, advantages of this method are as follows: very ex-cellent yield, no need for any anhydrous conditions, use of inexpensive metals, and very convenient, practi-cal and simple procedure.

Key words: 4β-azidopodophyllotoxin, synthesis, reduction, anticancer, 4β-aminopodophyllotoxin
