A general Pd-catalyzed double carbonylation of aryl iodides with secondary or primary amines to produce α-ketoamides at atmospheric CO pressure has been developed. This transformation proceeds successfully even at room temperature and in the absence of any ligand and additive. A wide range of aryl iodides and amines can be coupled to the desired α-ketoamides in high yields with excellent chemoselectivities
已经开发出在大气压CO压力下,普通的钯催化的碘化芳基碘与仲或伯胺的双羰基化反应,生成α-酮酰胺。即使在室温下且没有任何配体和添加剂的情况下,这种转化也能成功进行。各种各样的芳基碘化物和胺类可以以高收率与所需的α-酮酰胺以优异的化学选择性偶联。重要的是,目前的方法已被证明可用于生物活性分子和手性α-酮酰胺的合成。
