A palladium-catalyzed carbonylative synthesis of carboxamide substituted 2-pynones from methyl enynoates and nitroarenes has been developed. With nitroarenes as the nitrogen sources, and Mo(CO)6 as both CO surrogate and reductant, a wide range of carboxamide substituted 2-pynones were obtained in moderate to high yields with quite high functional group compatibility. Moreover, the late-stage modifications
已经开发出一种由烯烯酸甲酯和硝基芳烃通过钯催化羰基化合成甲酰胺取代的 2-吡喃酮的方法。以硝基芳烃为氮源,Mo(CO) 6作为CO替代物和还原剂,以中等到高产率获得了多种甲酰胺取代的2-吡喃酮,且具有相当高的官能团相容性。此外,还实现了天然分子的后期修饰。
