A number of linear quinazolinones fused to five-membered rings - benzimidazo[2,1-b]quinazolinones 8 and benzothiazolo[2,3-b]quinazolinones 10 - have been prepared from iminophosphoranes 4, derived from N-substituted o-azidobenzamides by a combination of t

6(5)H-Benzimidazoquinazolin-12-one was obtained in high yield by condensation of benzimidazole-2-sulfonic acid with anthranilic acid.Methods for the introduction of substituents selectively into the 5 and 6 positions of this heterocycle were develo
