One-pot conversion of azides to N-monomethylamines is described. Two optional protocols have been developed, which share the first stage, the reaction of an azide with (CH3)3P to generate the corresponding iminophosphorane. This Staudinger intermediate, thus generated, is either methylated with CH3I and hydrolyzed (method A), or treated with (HCHO) n and reduced with NaBH4 (method B), thereby giving the corresponding N-monomethylamine in high yield.
介绍了叠氮化物与 N-单甲基胺的单锅转化。已开发出两种可选方案,它们共享第一阶段,即叠氮化物与 (CH3)3P 反应生成相应的亚氨基磷烷。由此生成的施陶丁格中间体可以用 CH3I 进行甲基化并水解(方法 A),或者用 (HCHO) n 处理并用 NaBH4 还原(方法 B),从而以高产率得到相应的 N-单甲胺。
