Disclosed are intermediates of Sitagliptin, a preparation process thereof, and a process for synthesizing Sitagliptin using these intermediates. Sitagliptin is synthesized by using chiral amino compounds as a raw material, without having to build a chiral center with a chiral asymmetric catalytic hydrogenation, and high-pressure hydrogenation is avoided.
揭示了
西他列汀的中间体、其制备过程以及利用这些中间体合成
西他列汀的方法。
西他列汀是通过使用手性
氨基化合物作为原料合成的,无需通过手性不对称催化氢化建立手性中心,并且避免了高压氢化反应。
