介绍了一种实用、有效的酮内酯类抗生素头孢霉素(ABT-773)(1)的合成方法。有效的保护策略允许高产率,区域选择性C6-O-烷基化和随后的红霉素核的立体选择性修饰。ABT-773由市售红霉素A肟经10步制备而成。(C)2004爱思唯尔有限公司保留所有权利。
A practical and efficient synthesis of ketolide antibiotic cethromycin (ABT-773) (1) is described. An effective protection strategy allows high yielding, regioselective C6-O-alkylation and subsequent stereoselective modification of the erythromycin nucleus. ABT-773 was prepared in 10 steps from commercially available erythromycin A oxime. (C) 2004 Elsevier Ltd. All rights reserved.
