construction of π-conjugated polycyclic heteroarenes represents a significant task in the field of functional materials. A one-step oxidative tandem cyclization of aromatic acids with (benzo)thiophenes was developed to access planar sulfur-containing polycyclic heteroarenes. This protocol undergoes intermolecular cross-dehydrogenative coupling followed by intramolecular Friedel–Crafts acylation and provides
π-共轭多环杂芳烃的有效构建是功能材料领域的一项重要任务。开发了芳香酸与(苯并)噻吩的一步氧化串联环化来获得平面含硫多环杂芳烃。该方案经历分子间交叉脱氢偶联,然后进行分子内弗里德尔-克来福特酰化,并提供了从廉价反应物生成平面多环化合物的简便途径。合成的杂芳烃作为脂滴靶向探针表现出优异的性能,具有良好的生物相容性和光稳定性。
