合成路线1
该中间体在本合成路线中的序号：(X)Conversion of imidazolide (VII) into the cyclic carbamate (VIII) was carried out employing liquid ammonia in cold acetonitrile. The 3-cladinose moiety of (VIII) was then selectively removed by smooth acidic hydrolysis, yielding (IX). Subsequent oxidation of the 3-hydroxyl group of (IX) by means of N-chlorsuccinimide in the presence of dimethyl sulfide led to the ketolide compound (X). Palladium-catalyzed coupling of 3-bromoquinoline (XI) to the terminal acetylenic position of (X) furnished (XII). The title compound was finally obtained by methanolysis of the 2'-acetate group of (XII) at room temperature.
