Abstract
Easily accessible 1-aryl-2-aza-1,3-butadienes undergo a regioselective cyclocondensation with 2-(aminomethyl)aniline, giving rise to 1,3,5-benzotriazocines in good yields. The structure of the title compounds was proved with the aid of 1H and 13C NMR spectra and, in one case, single-crystal x-ray analysis.
