A facile and effective approach for the synthesis of 4-arylidene-2-phenyl-5(4H)-oxazolones has been developed. Under solvent-assisted grinding in the presence of 2,4,6-trichloro-1,3,5-triazine, catalytic triphenylphosphine, and sodium carbonate, dehydration–condensation of hippuric acid with aromatic aldehydes proceeded rapidly within minutes at room temperature to afford the products in good to excellent
已经开发了一种简便而有效的合成4-亚芳基-2-苯基-5(4 H)-恶唑酮的方法。在2,4,6-三氯-1,3,5-三嗪,催化三苯膦和碳酸钠存在下的溶剂辅助研磨下,室温下几分钟之内,马来酸与芳族醛的脱水-缩合反应迅速进行,从而得到产品的良率到优等。
