SERIES of dihydropyrimidine(thi)one derivatives were prepared, in …..good yields at room temperature by using a modified Biginelli reaction. The products were obtained through a one-pot three-component coupling of β-diketones, aldehydes and urea (or thiourea) in the presence of a catalytic amount of tetrachlorosilane (TCS). The effect of catalyst type, molar ratios of reactants and solvent type were also investigated; best results were obtained when TCS was employed as a catalyst and CH2Cl2 as a solvent at room temperature.
