(Alpha-aminoacyl)amino-substituted heterocycles and related compounds

N-Protected-(aminoacyl)benzotriazoles 1a-e, g, i, j, 1a'-c' convert heterocyclic amines of the following series: thiazoles (3a and 3a'), benzothiazoles (3b and 3b'), benzimidazoles (3c and 3c'), thiadiazoles (3d), pyrimidones (9a, b, a'), pyrazoles (11a, b), and pyridines (13a-g, 13d') under microwave irradiation, into N-substituted amides in yields of 40-98% (average 76%). N-Protected peptidoylbenzotriazoles 6a, b similarly afforded C-terminal N-protected dipeptidoyl amides 7a, b (52-60%).
