The cross-coupling reaction of cyclopropanol-derived ketone homoenolates bearing β-hydrogens with aryl and hetaryl bromides has been achieved for the first time. This reaction is high yielding, is broad in scope and uses a simple catalytic system. Notably, the proposed palladium homoenolates do not undergo β-hydride elimination to the corresponding α,β-unsaturated ketones.
首次实现了含有β-氢的环丙醇衍生的酮烯醇盐与芳基和杂芳基溴的交叉耦合反应。该反应产率高,适用范围广,并采用了一个简单的催化体系。值得注意的是,所提出的钯烯醇盐不会经历β-氢消除形成相应的α,β-不饱和酮。
