generated isocyanate with a nucleophile was established, which is safe, inexpensive, and suitable for large-scale synthesis. By this flow reaction in the Curtius rearrangement and recrystallization of the late-stage acetamide intermediate the third-generation synthesis of (-)-Oseltamivir has been established, which is efficient, practical, and safe.
建立了以三甲基甲硅烷基叠氮化物为叠氮化物源,然后用亲核试剂捕获生成的异氰酸酯的 Curtius 重排微流反应,该反应安全、廉价且适合大规模合成。通过库尔提斯重排和后期乙酰胺中间体的重结晶的流动反应,建立了(-)-奥司他韦的第三代合成方法,该方法高效、实用且安全。
