Promoted by triethylamine, α, β-unsaturated N-acylbenzotriazoles reacted with amino compounds in a variety of ways. Thus, N-cinnamoylbenzotriazoles reacting with aromatic amines afforded novel addition products β-benzotriazolyl amides 3, which might be normally formed from the alternative but unknown 1, 4-addition of benzotriazole to N- cinnamoylamides. The type 3 compounds could also result from the reaction between N- ...
