Abstract An efficient procedure was developed for direct preparation of aryl-substituted lactones from corresponding aryl carboxylic acids, which was promoted by ammonium iodide. In this protocol, aryl carboxylic acids were treated with ammonium iodide, potassium bromide, and oxidant Oxone in a mixture of acetonitrile and 2,2,2-trifluoroethanol (6:4) at room temperature for 12 h, resulting in corresponding
摘要 开发了一种在碘化铵促进下由相应的芳基羧酸直接制备芳基取代内酯的有效方法。在该协议中,芳基羧酸在乙腈和 2,2,2-三氟乙醇 (6:4) 的混合物中在室温下用碘化铵、溴化钾和氧化剂 Oxone 处理 12 小时,得到相应的芳基内酯。中等至良好的产量。图形概要
