摘要:
The invention relates to Sitagliptin intermediate compounds of formula (f), preparation methods and uses thereof. The compound of formula (f) are prepared by the following steps: compounds of formula (a) are subjected to electrophilic reaction with benzyl halides to form compounds of formula (b), which then react with compounds of formula (i) to form novel compounds of formula (e); Gignard agents formed from 2,4,5-trifluoro bromobenzene and magnesium metal react with compounds of formula (e) to afford compounds of formula (f), which are novel intermediate compounds for the preparation of Sitagliptin intermediates of formula (g). The compound of formula (f) was subjected to reduction by Pd/C, debenzylation, substitution of protecting group to form the compounds of formula (g). The mentioned compounds have the following structures, wherein, R is the protecting group of carboxyl, R 2 is (substituted) hydrocarbyl.
