A facile and efficient method was developed for the preparation of a variety of aryl, heteroaryl, and alkyl N-sulfinyl imines using 1,8-diazabicyclo[5.4.0]undec-7-ene. In addition to tert-butanesulfinamide, the condensation is also effective with p-toluenesulfinamide. The reaction was performed at room temperature and produces the corresponding N-sulfinyl imines in excellent yields in the absence of
开发了一种使用 1,8-二氮杂双环 [5.4.0] undec-7-ene 制备各种芳基、杂芳基和烷基 N-亚磺酰基亚胺的简便有效的方法。除叔丁烷亚磺酰胺外,缩合对甲苯亚磺酰胺也有效。该反应在室温下进行,并在不存在酸、金属和添加剂的情况下以极好的收率产生相应的 N-亚磺酰基亚胺。该方法也可用于以克规模制备 N-亚磺酰基亚胺。使用芳基和杂芳基醇与叔丁烷亚磺酰胺和对甲苯亚磺酰胺在室温下进行一锅合成,得到相应的 N-亚磺酰亚胺,收率良好。
