Full text not available from this repository. (Request a copy)Abstract
A facile one-pot synthesis of 5-unsubstituted dihydropyrimidinones from beta,gamma-unsaturated ketoesters in low melting L-(+)-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.
