A simple and efficient trifluoroacetic acid mediated protocol for ortho-amidomethylation of phenols in aqueous medium has been described. Developed protocol has a good substrate scope, involves mild reaction conditions, and products are obtained in good yields. The quantum chemical calculations were performed in implicit solvent (water) conditions, which helped in tracing the reaction mechanism and
已经描述了一种简单有效的三氟乙酸介导的在水性介质中苯酚的邻氨基甲基化方法。所开发的方案具有良好的底物范围,涉及温和的反应条件,并且以良好的产率获得产物。量子化学计算在隐式溶剂(水)条件下进行,这有助于追踪反应机理并获得关于可能的反应途径的见解,其中涉及N C键的形成并同时进行氢转移以生成最终产物。还证明了该方案对从酚,甲醛和苯乙烯一锅合成黄烷的适用性。
