oxygen-assisted palladium-catalyzed hydration reaction of alkynes is realized to prepare a series of o-acylacetanilide derivatives with high yield, and single regioselectivity under mild reaction conditions. This transformation is simple, practical, and can be performed on a gram scale. Evaluation of the mechanism shows that the reaction should involve an oxypalladation process, and the 1,3-oxazine compound
在此,实现了炔烃的酰胺氧辅助钯催化的水合反应,以高收率,在温和的反应条件下具有单区域选择性的方式制备了一系列邻酰基乙酰苯胺衍生物。此转换简单,实用,并且可以以克为单位执行。对该机理的评估表明,该反应应包括羰基缩合过程,并且已证明1,3-恶嗪化合物是关键中间体。
