The three-component synthesis of pyridazinones from aldehydes, arylhydrazines and 3-acryloyloxazolidin-2-one catalyzed by Cu(OTf)2 has been developed. This strategy exhibits high tolerance towards many functional groups including various aliphatic, aromatic and hetero-aromatic aldehydes to give 2,6-diaryl-4,5-dihydropyridazin-3(2H)-one products in moderate to high yields.
开发了Cu(OTf) 2催化醛类、芳基肼类和3-丙烯酰恶唑烷-2-酮类三组分合成哒嗪酮类化合物。该策略对包括各种脂肪族、芳香族和杂芳族醛在内的许多官能团表现出高耐受性,以中高产率生成 2,6-diaryl-4,5-dihydropyridazin-3(2 H )-one 产物。
