A simple, efficient, and environmentally benign method for a three-component reaction of an amine, an aldehyde or a ketone, and diethyl phosphite catalyzed by Amberlite-IR 120 resin has been developed to afford α-amino phosphonates in high yields and short reaction times under solvent-free reaction conditions. The major advantages of the present method are good yields, inexpensive, ecofriendly and
已开发出一种简单,有效且环境友好的方法,用于由Amberlite-IR 120树脂催化的胺,醛或酮与亚磷酸二乙酯的三组分反应,从而以高收率和短反应时间提供α-氨基膦酸酯无溶剂反应条件下的反应时间。本方法的主要优点是产率高,价格便宜,生态友好且可重复使用的催化剂,温和且无溶剂的反应条件以及对基质中存在的各种功能的耐受性。
