摘要:

本文报道了一种以10-去乙酰基巴卡丁III为起始原料合成卡巴他赛的新方法。 路线中使用了温和的条件对底物7-羟基进行甲醚化, 从而避免了7β-羟基在强碱性条件下的差向异构化。该路线共6步, 总收率为20%。

关键词: 卡巴他赛, 7-羟基甲基化

Abstract:

A new route for the synthesis of cabazitaxel (Javanta®) starting with 10-deacetylbaccatin III was developed. In this new procedure, a mild condition for the methylation of 7-OH was applied, thus the epimerization of 7β-OH under basic conditions was reduced. The total yield of this 6-step synthesis is 20%.

Key words: Cabazitaxel, 7-OH Methylation
