A novel, efficient route to biologically and pharmaceutically important o-(dimethylamino)aryl ketones, acridones, acridinium salts, and 1H-indazoles has been developed starting from readily available hydrazones of aldehydes and o-(trimethylsilyl)aryl triflates. The reaction proceeds through arynes under mild conditions, tolerates a wide range of functional groups, and provides the final products in
已经从容易获得的醛腙和邻(三甲基甲硅烷基)芳基三氟甲磺酸酯开始,开发了一种新的、有效的生物和药学上重要的邻(二甲基氨基)芳基酮、吖啶酮、吖啶盐和 1 H-吲唑的途径。该反应在温和条件下通过芳烃进行,可耐受范围广泛的官能团,并以良好至极好的收率提供最终产物。
