The synthesis of 4-acyl-NH-1,2,3-triazoles has been accomplished with high efficiency through the cycloaddition reactions between N,N-dimethylenaminones and tosyl azide. This method is featured with extraordinary sustainability by employing water as the sole medium, free of any catalyst or additive, authentically mild conditions (40 °C stirring) as well as practical scalability.
通过N,N-二甲基亚氨基酮与甲苯磺酰基叠氮化物之间的环加成反应,已经高效地完成了4-酰基-NH-1,2,3-三唑的合成。该方法以水为唯一介质,不含任何催化剂或添加剂,具有温和的条件(40°C搅拌),具有实用的可扩展性,具有非凡的可持续性。
