An efficient and scalable synthesis of an antidiabetic drug, tofogliflozin (1), which was identified as a highly selective sodium glucose cotransporter 2 (SGLT2) inhibitor, is described. A key factor in the synthesis of 1 was the selection of the purpose-designed protecting group, which plays a strategic role in protection, chemoselective activation, and crystalline purification. The developed and
描述了一种高效,可扩展的抗糖尿病药物tofogliflozin(1)的合成,该药物被确定为高选择性钠葡萄糖共转运蛋白2(SGLT2)抑制剂。合成1的关键因素是选择专门设计的保护基,该保护基在保护,化学选择性活化和晶体纯化中起着战略性作用。通过开发和优化的方法,无需任何柱色谱法就可以以十克规模制备1。
