Copper(II) Sulfamate: An Efficient Catalyst for the One-Pot Synthesis of 3,4-Dihydropyrimidine-2(1H)-ones and thiones
A simple, efficient procedure for the one-pot Biginelli condensation reaction of aldehydes, β-ketoesters and urea or thiourea employing copper(II) sulfamate as a novel catalyst is described. Compared to the classical Biginelli reaction conditions, the present method has the advantages of good yields...
