|Abstract:||Various substituted 3, 4-dihydropyrimidin-2(1<i style="">H</i>)-ones have been synthesized in a one pot reaction of <img src='/image/spc_char/beta.gif' border=0>-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.|
