| Abstract: | Various
substituted 3, 4-dihydropyrimidin-2(1H)-ones
have been synthesized in a one pot reaction of  -ketoesters, aldehydes and
urea using cobalt chloride hexahydrate or manganese chloride tetrahydrate or
tin chloride dihydrate under microwave irradiation in excellent yields without
the addition of any proton source or any additive and without any side
reactions as observed by Biginelli and others. |
