RESUMEN

A facile one-pot synthesis of 5-unsubstituted dihydropyrimidinones from ß,Î³-unsaturated ketoesters in low melting Ê-(+)-tartaric acid-N,N-dimethylurea mixtures is reported. This solvent-free method is very general and provides easy access to 5-unsubstituted dihydropyrimidinone-4-carboxylate derivatives in good yields.

Palabras clave
