An original cobalt-catalyzed ynamide carbozincation leading mainly to diverse 3-aryl enamides with mild reaction conditions and good functional-group tolerance has been developed. This reaction displays an excellent regio- and total stereoselectivity and opens the way to appealing synthetic applications. Moreover, this approach allows the selective synthesis of biologically relevant 3,5-disubstituted oxazolone frameworks.
一种新型钴催化的炔酰胺碳锌化反应,在温和的反应条件下和很好的官能团容忍度下,主要得到各种 3-芳基烯酰胺。该反应表现出极好的区域和立体选择性,并为有吸引力的合成应用开辟了道路。此外,这种方法还可以选择性地合成具有生物相关性的 3,5-二取代恶唑酮骨架。
