N-heterocyclic scaffolds is reported. In this strategy, a tandem approach of two highly efficient synthetic reactions, click and cross-dehydrogentive coupling reactions, with high atom economy were employed to obtain the target N-fused scaffolds. Being highly functional group tolerable, this method has broad substrate scope. Interestingly, some of these derivatives showed strong white solid-state fluorescence
本文报道了一种一锅法合成四环三唑-哌嗪-喹唑啉酮融合的 N-杂环支架的方法。在该策略中,采用两种高效合成反应的串联方法,即点击和交叉脱氢偶联反应,具有高原子经济性,以获得目标 N-融合支架。由于具有高度官能团耐受性,该方法具有广泛的底物范围。有趣的是,其中一些衍生物显示出强烈的白色固态荧光。
