An ultrasound promoted easy, efficient, and environment friendly process has been devised for the synthesis of α-aminophosphonates within seconds through a one-pot three-component condensation of the aldehydes, amines, and triethylphosphite. The desired products were obtained in excellent yields and in high purity under solvent-free and catalyst-free conditions. Study with various aldehydes and amines
已经设计了超声促进的简单,有效和环境友好的方法,用于通过醛,胺和亚磷酸三乙酯的一锅式三组分缩合在几秒钟内合成α-氨基膦酸酯。在无溶剂和无催化剂的条件下,可以以极高的收率和高纯度获得所需的产物。对各种醛和胺的研究表明,超声辐射在α-氨基膦酸酯的直接合成中起着关键作用。
