NON-CONVENTIONAL SYNTHESES OF HETEROCYCLIC COMPOUNDS: A NEW SYNTHESIS OF 1,3,4-BENZOTRIAZEPINE DERIVATIVES

Article abstract of DOI:10.1016/S0040-4039(00)86752-0

4,5-Dihydro-1,3,4-benzotriazepines were obtained in good yields by intramolecular thermal cyclization of arylazoanils with methyl or ethyl groups in the ortho positions of the aromatic ring on the imine nitrogen.
