the other two were established (or modified) via three highly stereoselective transformations: Luche reduction (dr: 97/3), dynamic kinetic resolution of anomeric hemiacetal (dr: 95/5), and Lewis acid-promoted thiolation (dr: 1000/1). Global deprotection of the resulting penultimate intermediate with catalytic sodium methoxide followed by recrystallization furnishes sotagliflozin. The longest linear sequence
描述了有效的制造工艺索格列净(LX4211)的研究,索格列净是钠-葡萄糖共转运蛋白1/2的双重抑制剂(SGLT-1 / 2)用于糖尿病的治疗。Sotagliflozin在碳水化合物核心上具有五个连续的手性中心,两侧是硫醚基和联芳基部分。从原料1-木糖获得三个手性中心,而另外两个则通过三个高度立体选择性的转化:Luche还原(dr:97/3),异头半缩醛的动态动力学拆分(dr:95/5)和Lewis酸促进的硫醇化(dr:1000/1)。用催化的甲醇钠对所得的倒数第二个中间体进行整体脱保护,然后重结晶,从而提供了索格列净。最长的线性序列由1-木糖形成10步,总产率为40%。此过程已针对数百公斤批次执行,以满足原料药开发需求。
