Abstract:
One pot condensation of ethylacetoacetate with various para and ortho substituted aldehydes and urea or thiourea by SnCl2.2H2O affords eight different substituted 3,4-dihydropyrimidine ones/thiones. Further we prepared acetylated 3,4-dihydropyrimidine ones/thiones, on treatment of 3,4-dihydropyrimidine ones/thiones with acetic anhydride using zinc chloride as a catalyst. Calcium channel blocker activity shows that synthesized compounds have moderate activity.
