|Abstract:||Alkylideno/arylideno bis ureas 1 synthesized by ureidoalkylation in the presence of alcohols–which on treatment with p-aminobenzoic acid results in 4-aryl-6-carboxylato-1,2,3,4-tetrahydroquinazolines 2. Reaction of 2 with benzoin in presence of polyphosphoric acid yields 4-aryl-8,9-diphenyl-1,4 dihydro-3H, 7-oxo-1,3-diaza anthracene-2,6-dione 3. Condensation of 3 with aromatic primary amine affords N-aryl-8,9-diphenyl (-2-oxo-pyrido [g]-4-aryl-2-oxo-1,3-dihydro quinazolines 4. The new compound 4 has been screened for their antibacterial and antifungal activities.|
