A simple, efficient and mild methodology for the synthesis of 1,3,2-benzodiazaborininones [R-B(aam)] from boronic acids and anthranilamides on ethyl acetate is described. A series of 1,3,2-benzodiazaborininones were prepared in moderate to excellent yields at room temperature without dehydrating agents, metal catalysts, corrosive acids or other additives. Meanwhile, a multi-gram scale reaction is also
描述了一种简单、高效且温和的方法,用于在乙酸乙酯上从硼酸和邻氨基苯甲酰胺合成 1,3,2-苯并二氮杂硼啉酮 [RB(aam)]。在没有脱水剂、金属催化剂、腐蚀性酸或其他添加剂的情况下,在室温下以中等到优异的收率制备了一系列 1,3,2-苯并二氮杂硼啉酮。同时,还进行了多克规模的反应,保证了反应的可扩展性,并且可以通过简单的过滤方便地分离产物。
