摘要：

A fast and efficient Biginelli synthesis of 3,4-dihydropyrimidin-2-(1H)-ones (or thiones) by the reaction of aromatic aldehydes, -dicarbonyls, and urea/thiourea using NaHSO4H2O/ultrasound system is presented. The reactions were carried out in refluxing n-hexane/CH3CN (2.5:0.5mL) to afford the products in excellent yields.
