isolation procedure is simple, environmentally friendly, and is performed with no need for chromatographic purification of secondary amides due to high yields. In this report, primary amines were used in most examples. However, the developed procedure seems to be applicable for secondary amines as well. The methodology produces a limited amount of wastes, and a catalyst can be easily separated. This highly
酰胺键是化学制药工业中最有趣和最丰富的生命分子和产品之一。在这项工作中,我们描述了一种在无溶剂条件下使用微量硝酸铈铵 (CAN) 作为催化剂从羧酸和胺直接合成酰胺的方法。该反应在开放式微波反应器中进行,与迄今为止文献中报道的由酸和胺直接合成酰胺的其他方法相比,可以快速有效地获得相应的酰胺。酰胺产物的分离过程简单、环保,并且由于产率高,不需要二级酰胺的色谱纯化。在本报告中,大多数实施例中使用了伯胺。然而,开发的程序似乎也适用于仲胺。该方法产生的废物量有限,而且催化剂很容易分离。这种高效、稳健、快速、无溶剂和额外无试剂的方法为开发理想的酰胺键形成绿色方案提供了重大进步。
