elemental sulfur-mediated oxidative condensation of nitriles and 2-(aminomethyl)anilines was developed. The reaction was carried out under metal-/solvent-free conditions, tolerates a wide range of functional groups to provide the corresponding products in 56%-91% yield, and can be performed on a gram-scale. The UV/Vis absorption and fluorescence spectra of several product derivatives were measured to study
开发了一种通过元素硫介导的腈和 2-(氨基甲基)苯胺的氧化缩合合成喹唑啉的策略。该反应在无金属/无溶剂条件下进行,耐受范围广泛的官能团,以56%-91%的收率提供相应的产物,并且可以在克级进行。测量了几种产品衍生物的 UV/Vis 吸收和荧光光谱,以研究它们的光物理性质。
