A new method for converting easy availability starting materials 2-(2-oxoindolin-3-yl)acetonitrile, arylboronic acids, and alcohols into 2-arylquinoline-4-carboxylates is reported. The procedure involves a three-component addition/ring expansion/esterification reaction in the presence of Pd(II) catalyst with high functional group tolerance under mild conditions. In addition, the photophysical properties
报道了一种将易于获得的起始材料 2-(2-oxoindolin-3-yl) 乙腈、芳基硼酸和醇类转化为 2-芳基喹啉-4-羧酸酯的新方法。该过程涉及在温和条件下在具有高官能团耐受性的 Pd(II) 催化剂存在下的三组分加成/扩环/酯化反应。此外,研究了所得产物的光物理性质,并表现出优异的极性敏感荧光性质和 AIE 性质。
