摘要
Borax/phosphorous oxychloride (BPO) is found to be a new efficient catalyst for three component coupling of beta-dicarbonyl compounds, aldehydes and urea (or thiourea) to afford the corresponding dihydropyrimidinones or their sulfur analogues. The reaction proceeds efficiently under solvent-free conditions with excellent yields.
