Non Conventional Syntheses of Heterocyclic Compounds. 2. Synthesis of 1H-4,5-Dihydro-1,3,4-Benzotriazepine Derivatives

Fusco, Raffaello,Marchesini, Alessandro,Sannicolo, Franco

, p. 1795 - 1799 (2007/10/02)

Arylazoanils carrying aromatic methyl or ethyl groups in the position ortho to the imine function thermally cyclize to give 1H-4,5-dihydro-1,3,4-benzotriazepine derivatives in fairly good yields.A study of the effect of the substituents on both the aryl rings is reported.The reaction is interpreted as an internal oxo-reduction process.
