Abstract
[chemical reaction: see text]. An efficient Yb(OTf)3-promoted palladium-catalyzed oxidative cyclization of gamma-heteroalkenyl beta-keto amides has been developed. Under simple aerobic condition, a variety of six-, seven-, and eight-membered-ring N- and O-heterocycles were obtained regioselectively in excellent yield.
摘要
[化学反应：见正文]。已开发出一种高效的Yb(OTf)₃促进的钯催化γ-杂烯基β-酮酰胺的氧化环化反应。在简单的有氧条件下，可区域选择性地以优异产率得到多种六元、七元和八元的N-和O-杂环化合物。
