efficient one-pot, three-component synthetic method for the preparation of coumarin-3-carboxamides was carried out by the reaction of salicylaldehyde, aliphatic primary/secondary amines, and diethylmalonate. The protocol employs piperidine-iodine as a dual system catalyst and ethanol, a green solvent. The main advantages of this approach are that it is a metal-free and clean reaction, has low catalyst loading
通过水杨醛、脂肪族伯/仲胺和丙二酸二乙酯的反应,进行了一种简单、高效的一锅三组分合成香豆素-3-羧酰胺的制备方法。该协议采用哌啶碘作为双系统催化剂和乙醇,一种绿色溶剂。这种方法的主要优点是它是一种无金属且清洁的反应,催化剂负载量低,并且不需要繁琐的后处理。
