摘要
报道了水相中硫酸氢钠催化的乙酰乙酸酯、醛和脲(硫脲)参与的Biginelli型反应,在超声波促进下高效地合成11个3,4-二氢嘧啶酮衍生物,收率80%~93%,其结构经1H NMR和HR-MS确证。
Eleven 3,4-dihydropyrimidin-2( 1H)-ones were efficiently synthesized by aqueous Biginelli reaction of β-ketoester,aldehyde and urea( or thiourea) catalyzed by Na HSO4 under ultrasonic irradiation with the yields of 80% ~ 93%. The structures were confirmed by1 H NMR and HR-MS.
