Phenylboronic Acid as Efficient and Eco-Friendly Catalyst for the One-Pot, Three-Component Synthesis of α-Aminophosphonates under Solvent-Free Conditions
A simple, mild, and efficient one-pot, three-component synthetic method has been developed for the preparation of α-aminophosphonates using phenylboronic acid as catalyst undersolvent-freeconditions at 50 °C. The process involves the reaction of carbonylcompounds (aldehydes or ketones) with benzylamine and dimethyl phosphite. A wide range of carbonylcompounds are compatible with this reaction,
开发了一种简单、温和、高效的一锅三组分合成方法,以苯基硼酸为催化剂,在 50 °C 无溶剂条件下制备 α-氨基膦酸酯。该过程涉及羰基化合物(醛或酮)与苄胺和亚磷酸二甲酯的反应。广泛的羰基化合物与该反应相容,可在短时间内以中等至极好的收率生产叔和季 α-氨基膦酸酯。
