Abstract

This study reports the reduction of α,β-unsaturated ketones 4a–g, formed by condensation of arylglyoxals 2a–g with 1,3-dimethylbarbituric acid (3) by L-cysteine (5) in the presence of phosphotungstic acid as a catalyst. This reaction leads to the formation of 5-[2-aryl-2-oxoethyl]-1,3-dimethylpyrimidine-2,4,6-triones 6a–g, with no sign of any heterocyclic product formation. The structure of compound 6f was confirmed by X-ray crystallography.
