A novel clean, one-pot syntheses of 3-arylquinazolin-4(3H)-ones and quinoxalino[2,1-b]quinazoline-6,12(5H)-diones via PPA-mediated coupling of N-(2-carboxyphenyl)oxalamides with arylamines and 1,2-benzenediamines have been developed. Under mild reaction conditions with use of Na2S2O4 the benzimidazo[2,1-b]quinazolin-12-ones were achieved in good yield from 3-(2-nitrophenyl)quinazolin-4-ones.
