INTERMEDIATES OF SITAGLIPTIN AND PREPARATION PROCESS THEREOF
-
Paragraph 0160; 0161, (2013/10/22)
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.
