Ascorbic acid-Catalyzed One-Pot Three-Component Biginelli Reaction: A Practical and Green Approach towards Synthesis of 3,4-dihydropyrimidin- 2(1H)-ones/thiones
Abstract : An efficient one-pot synthesis of 3,4-dihydropyrimidin-2(1H)-ones/thiones via a three-component Biginelli condensation of aldehyde, ethyl acetoacetate, and urea or thiourea in the presence of a catalytic amount of ascorbic acid (5 mol %) is described. The reaction proceeded efficiently under solvent-free conditions at 80 °C to afford the desired products in moderate to good yields.
