Benzotriazole-assisted Synthesis of α-Acylaminonitriles and a Conceptually Novel Method for Peptide Elongation

Katritzky, Alan R.,Urogdi, Laszlo

, p. 1853 - 1857 (2007/10/02)

A general method for the synthesis of α-acylamino nitriles is reported.Initially, the adducts resulting from Mannich-type condensation of benzotriazole with an aldehyde and an amide are prepared.These undergo elimination of benzotriazole with cyanide to g
