Solvent free synthesis of 3,4-dihydropyrimidine-2-(1H)-ones/thiones catalyzed by N,O-bis(trimethylsilyl)acetamide and dicyclohexyl carbodimide

Solvent free synthesis of 3,4-dihydropyrimidine-2-(1H)-ones/thiones catalyzed by N,O-bis(trimethylsilyl)acetamide and dicyclohexyl carbodimide

We report herein, the usage of N,O-bis(trimethylsilyl)acetamide (BSA) and dicyclohexyl carbodimide (DCC) as two new catalysts for three component condensation of an aldehyde, ethyl acetoacetate and urea/thiourea under solvent free conditions at 100 °C to afford the corresponding 3,4-dihydropyrimidin...
