range of readily available α-phosphate enamides were subjected to (hetero)aromatic dioxazaborocanes (DABO boronates), providing the desired α-functionalized enamides in high yields via palladium-catalyzed cross-coupling reactions. Notably, the reaction proceeds in the presence of a slight excess of boron derivatives and tolerates cyclic, nonaromatic and/or electron-rich enamides.
一系列易于获得的 α-磷酸烯酰胺经过(杂)芳族二恶唑硼烷(DABO 硼酸酯)处理,通过钯催化的交叉偶联反应以高产率提供所需的 α-官能化烯酰胺。值得注意的是,该反应在略微过量的硼衍生物存在下进行,并且可以耐受环状、非芳香族和/或富含电子的烯酰胺。
