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

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
