quinoline fragment of simeprevir are described. Both approaches are based on the synthesis of methyl 4-hydroxy-7-methoxy-8-methylquinoline-2-carboxylate, protection of its 4-hydroxyl group, and construction of the thiazole ring from the ester group at the 2-position. The last step is acid deprotection of the 4-hydroxyl protecting group. Two synthetic approaches to the achiral quinoline fragment of simeprevir
献给我的朋友和令人钦佩的人在他90的一次是阿尔弗雷德·贝德博士日生日(SR)。 抽象 描述了两种合成方法来合成西美普韦的非手性喹啉片段。两种方法都基于4-羟基-7-甲氧基-8-甲基喹啉-2-羧酸甲酯的合成,其4-羟基的保护以及噻唑环在2-位的酯基的构建。最后一步是对4-羟基保护基进行酸脱保护。 描述了两种合成方法来合成西美普韦的非手性喹啉片段。两种方法都基于4-羟基-7-甲氧基-8-甲基喹啉-2-羧酸甲酯的合成,其4-羟基的保护以及噻唑环在2-位的酯基的构建。最后一步是对4-羟基保护基进行酸脱保护。
