A highly efficient method has been developed for synthesis of 7,9-disubstituted-6,7-dihydro-5H-benzo[h]thiazolo[2,3-b]quinazolines via multicomponent one-pot two-step tandem reaction involving 1-tetralone, arylaldehydes, thiourea, and 4-chlorophenacyl bromide/(3-bromoacetyl)coumarin utilizing p-toluenesulfonic acid as catalyst in glacial acetic acid under reflux conditions. Analytically pure products are formed with excellent yield and short reaction time. All the synthesized compounds were confirmed by their spectral and elemental analyses.
