The present invention discloses a process for efficient production of 2-amino-5-hydroxypropiophenone corresponding to the AB ring part of camptothecin (CPT) skeleton, which is a key intermediate useful for the total synthesis of camptothecin analogs including 7-Ethyl-10-hydroxy camptothecin and novel intermediates thereof.
本发明揭示了一种高效生产2-
氨基-5-
羟基丙酮苯甲酰对应于
喜树碱(C
PT)骨架的AB环部分的方法,该方法是一种有用的关键中间体,可用于合成包括
7-乙基-10-羟基喜树碱和其新型中间体在内的
喜树碱类似物的总合成。
