An efficient asymmetric synthesis of Sitagliptin, a new DPP-IV inhibitor for the treatment of type 2 diabetes mellitus has been developed. The beta-amino acid fragment of Sitagliptin was prepared by asymmetric Michael addition of the corresponding α, β-unsaturated ester to (R)-(α-methylbenzyl)benzylamine followed by a two-step elaboration to obtain N-boc beta-amino ester. Hydrolysis of the ester and
已开发出一种有效的不对称合成西格列汀,一种用于治疗 2 型糖尿病的新型 DPP-IV 抑制剂。Sitagliptin 的 β-氨基酸片段是通过将相应的 α, β-不饱和酯与 (R)-(α-甲基苄基) 苄胺不对称迈克尔加成,然后两步合成得到 N-boc β-氨基酯来制备的. 在 N-boc 基团裂解和盐形成后,酯的水解和与三唑并哌嗪的偶联得到西格列汀。九个步骤的总产率为31%。
