effect
Vigliptin is a selective, competitive and reversible inhibitor of DPP24
Synthesis method L-proline is protected by di-tert-butyl dicarbonate, and then carbonyl amination with ammonia gas occurs under the action of 1-(3-dimethylaminopropyl) -3-ethylcarbodiimide (EDC), and then L-proline (intermediate 4) is obtained by removing Boc protection group with hydrochloric acid. L-proline Chemicalbook amide is acylated to (S) -chloro-acetyl-2-aminoacylpyrrolidine (intermediate 2), dehydrated to (S) -n-chloro-acetyl-2-cyanopyrrolidine (intermediate 3), and then nucleophilic substitution reaction with 3-amino-1-amantadanol (4) is performed to obtain Vigagliptin.
