摘要: 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.
摘要翻译: 公开了西他列汀的中间体,其制备方法以及使用这些中间体合成西他列汀的方法。 西他列汀以手性氨基化合物为原料合成,不需要用手性不对称催化氢化反应形成手性中心,避免了高压氢化。
