✦ Synopsis

Novel

5a,10,14b,15-tetraaza-benzo[a]

indeno [1,2-c]anthracen-5-one and benzimidazo[1,2-c]quinazoline derivatives were synthesised in good yields in two or three steps from 2-(2-aminophenyl)indole and 2-(2aminophenyl)benzimidazole. Microwave irradiation in homogeneous phase or in dry media was used in order to improve reactions where conventional heating (metal or oil bath) was limited.
