Abstract: Abstract A green and efficient method is described for the solvent free synthesis of 3,4-dihydropyrimidin-2(1H)-ones through one-pot three-component condensation of ethyl acetoacetate, an aryl aldehyde, and urea using mesoporous MCM-41 supported ammonium dihydrogen phosphate (NH4H2PO4/MCM-41)… read more here.
