Synthesis of novel 5a,10,14b,15-tetraaza-benzo[a]indeno[1,2-c]anthracen-5-one and benzimidazo[1,2-c]quinazoline derivatives under microwave irradiation
Novel 5a,10,14b,15-tetraaza-benzo[a]indeno[1,2-c]anthracen-5-one and benzimidazo[1,2-c]quinazolinederivatives were synthesised in good yields in two or three steps from 2-(2-aminophenyl)indole and 2-(2-aminophenyl)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.
新型5a,10,14b,15-四氮杂-苯并[ a ]茚并[1,2 - c ]蒽-5-酮和苯并咪唑并[1,2 - c ]喹唑啉衍生物可以从两步或三步合成2-(2-氨基苯基)吲哚和2-(2-氨基苯基)苯并咪唑。为了改善常规加热(金属或油浴)受限的反应,使用了均相或干燥介质中的微波辐照。
