Synthesis of 2(1H)-Pyridones From 2H-Pyran-2-ones 5-Substituted and 4,5-disubstituted 2(1H)-pyridones (13 examples) with formyl, acyl, alkoxycarbonyl, and trifluoromethyl groups in the 5 position were prepared in 16-97% yield by amination of the corresponding 2H-pyran-2-ones with hexamethyldisilazane or alkyl(trimethylsilyl)amines.
从2H-吡喃-2-酮合成2(1H)-吡啶酮 5-取代和4,5-二取代的2(1H)-吡啶酮(13个例子)通过将相应的2H-吡喃-2-酮与六甲基二硅氨或烷基( trimethylsilyl)胺进行胺化反应,在16%-97%的收率下制备了具有甲醛基、酰基、烷氧羧基和三氟甲基的5位取代基。
