Popis:	Amines read with N-cinnamoylbenzotriazoles to afford either β-amino-N-acylbenzotriazoles or cinnamides depending on the structure of the amines. Aromatic amines react with N-cinnamoylbenzotriazoles via 1,4-addition to give β-amino-N-acyl-benzotriazoles in good yields. For o-phenylenediamine, the 1,4-addition products were further acylated to provide a facile route to substituted 1,3,4,5-tetrahydro-1,5-benzodiazepine-2-ones. Aliphatic amines, however, react exclusively through the 1,2-addition pathway to produce cinnamides in good yields.
