The synthesis of carbohydrate-based glycogen phosphorylase inhibitors is attractive for potential applications in the treatment of type 2 diabetes. A titanium-mediated synthesis led to a benzoylated C-glucosylated cyclopropylamine intermediate, which underwent a benzoyl migration to afford the corresponding 2-hydroxy-C-glycoside. X-ray crystallographic studies revealed a unit cell composed of four
基于碳水化合物的糖原磷酸化酶抑制剂的合成对于治疗2型糖尿病具有潜在的吸引力。钛介导的合成产生了苯甲酰化的C-葡萄糖基化的环丙胺中间体,该中间体经历了苯甲酰基的迁移,从而提供了相应的2-羟基-C-糖苷。X射线晶体学研究表明,由四个分子组成的晶胞是通过两个氢键连接的成对的二聚体。在Zemplen条件下,苯甲酸酯的脱保护得到糖原磷酸化酶抑制剂候选物,其对糖原磷酸化酶的抑制作用较弱(2.5mM时为16%)。
