A sequential one-pot three-component microwave-assisted reaction for the efficient and regioselective synthesis of unprecedented polysubstituted 2-hydroxypyridines has been reported. In brief, 1H-indene-1,3(2H)-dione was reacted with acetamide in the presence of NaOH to give N-(1-oxo-1H-inden-3-yl)acetamide, which was treated in situ with aromatic aldehydes to build up the 2-hydroxy-4-aryl-5H-indeno[1
已经报道了用于高效和区域选择性合成前所未有的多取代的 2-羟基吡啶的顺序一锅三组分微波辅助反应。简而言之,1 H-茚-1,3( 2H )-二酮在 NaOH 存在下与乙酰胺反应生成N- (1-氧代-1 H-茚-3-基)乙酰胺,与芳香醛原位合成2-羟基-4-芳基-5 H-茚并[1,2 - b ]吡啶-5-酮,不使用任何氧化剂和中间体的分离。
