Abstract

An efficient solvent-free protocol for the synthesis of 3,4-dihydropyrimidine-2-(1H)-one by the one-pot condensation of aldehyde, ethyl acetoacetate and urea using Li(glycine)(CF₃SO₃) as a reusable acidic ionic liquid is reported. These reactions have the advantages in this work of clean reaction, simple purification, short reaction time and high yields.
