A practical strategy for the synthesis of diazabenz[e]aceanthrylene-based heterocycles is reported. The key step in this approach is a microwave-assisted condensation and cyclisation reaction between an anthranilic acid derivative and a 2′-carbomethoxy substituted N-aryl lactam. The scope of the reaction has been explored as a function of both the nature and position of substituents in both components
报道了一种合成基于二氮杂[ e ]乙炔基杂环的实用策略。该方法的关键步骤是邻氨基苯甲酸衍生物与2'-羰甲氧基取代的N-芳基内酰胺之间的微波辅助缩合和环化反应。已经根据两种组分中取代基的性质和位置以及内酰胺环尺寸的变化来探索反应的范围。使用NMR,X射线晶体学和计算技术描述并探索了整个化合物集合中观察到的有趣的结构和光谱变化。
