We report a new catalytic synthesis of α-pyridones and 3(2H)-isoquinolones from readily available 3-en-5-ynyl nitrones and o-alkynylphenyl nitrones; the reaction mechanism is proposed to involve iminyl ketene species through an oxygen transfer process.
我们报道了一种新的催化合成α-吡啶酮和3(2H)-异喹啉酮的方法,该方法使用易于获得的3-烯-5-炔基硝酮和邻-炔基苯基硝酮作为原料;反应机理被提出涉及通过氧转移过程形成的亚胺基碳烯物种。
