A simple and highly efficient protocol for the AcOH-catalyzed three-component reaction among nitroalkenes, difluoroethylamine and tert-butyl nitrite through cascade aza-Michael addition/N-nitrosation has been developed. A range of CF2HCH2-containing N-nitrosoamines were obtained in good to excellent yields. This approach features easily available cheap materials, without using additional organic solvents
已开发出一种简单高效的方案,可通过级联氮杂-迈克尔加成/ N-亚硝化反应在硝基烯烃,二
氟乙胺和
亚硝酸叔丁酯之间进行AcOH催化的三组分反应。以良好至优异的产率获得了一系列含CF 2 HCH 2的N-亚
硝基胺。这种方法的特点是易于获得的廉价材料,无需使用其他有机溶剂,在室温下操作简单,克级可扩展制备以及功能多样的产品。
