An efficient and convenient procedure has been developed for the synthesis of some new octahydroquinazolinones 5a-p in good yields. They have been achieved by the reaction between corresponding tetrazolo[1,5-a] quinoline-4-carbaldehyde 2a-d, dimedone or cyclohexane-1, 3-dione 3a-b and (thio) urea 4a-b in the presence of concentrated HCl in ethanol. The structures of new compounds have been evaluated on the basis of elemental analysis, FT-IR, H-1 NMR and C-13 NMR spectral data. They have also been screened for their antimicrobial activities.
