Abstract:

This paper describes the synthesis of pyrimido annulated analogues of carbazolo and azacarbazolo condensed aza-acridines respectively by the cyclocondensation of corresponding enol ether,chalcone, oxoketene dithioacetal and dimethyl aminomethylene ketone derivatives with urea, thiourea, acetamidine and guanidine respectively. The structures of all the compounds have been established on the basis of their elemental analysis and (IR, 1HNMR and MS) spectral data.
