A facile synthesis of 2-alkyl-3-α-carboxy-α-styryl/heterylvinyl quinazolin-4(3H)-ones and 3-arylidene/heterylmethylidene-4- aroyl-1H-[1,4]benzodiazepine-2,5(3H,4H)-diones and their transformation into novel heterocyclyl and heterocyclo analogues

Condensation of 2-methyl-/2-ethyl- and 2-phenyl-/p-tolyl-4-arylidene-/ heterylmethylidene-2-oxazolin- 5-ones (γ-azlactones) 2 with o-aminobenzamide 1 in acetic acid resulted in the formation of two entirely different heterocyclic systems, differently substituted quinazoline compounds, 2-methyl-/2- ethyl-3-α-carboxy-α-styryl-/β-heteryl-α- carboxyvinyl-quinazolin-4(3H)-ones 3a-3e and 3′a-3′e and differently substituted 1,4-benzodiazepine compounds, 3-arylidene-/heteryl methylidene-4-aroyl-1H- [1,4]benzodiazepine-2,5(3H,4H)-diones 7a-7e and 7′a-7′e. Compounds 3a-3e and 3′a-3′e have been converted into compounds, 4a-4e and 4′a-4′e; 5a-5e, and 5′a-5′e; and 6a-6e and 6′a-6′e through different transformations. Benzodiazepines, 7a-7e and 7′a-7′e, on condensation with o-phenylenediamine have generated three novel heterocyclic systems 8a-8e and 8′a-8′e; 9a-9e and 9′a-9′e; and 10a-10e and 10′a-10′e..
