本文介绍了一种用氰基甲酸甲酯直接酯化胺的简便方法。在温和和中性条件下,该菌株获得了中到高产。因此,在室温下获得甲酰胺2a-f、2 i-m。在乙醇胺的情况下,实现了化学选择性的N-甲基化。硝基苯胺的取代反应和醇的O-取代反应只有在催化量的咪唑存在下才能成功,分别得到2g,h和3a-e。
Abstract A simple method for the direct formylation of amines using cyanomethyl formate is described. The formylation succeeds in moderate to high yields under mild and neutral conditions. Thus, formamides 2a-f, 2i-m are obtained at room temperature. A chemoselective N-formylation is achieved in the case of ethanolamine. The formylation of nitroanilines and the O-formylation of alcohols only succeeds in the presence of a catalytic amount of imidazole leading to 2g,h and 3a-e, respectively.
