An efficient copper-catalyzed inter/intramolecular oxy/aminoarylation of γ-hydroxy/aminoalkenes with diaryliodonium triflates is reported. Simple activation of these arylating agents with copper(II) triflate in dichloromethane triggers a smooth activation of the alkene, which is simultaneously trapped by the internal nucleophile, yielding, depending upon its nature, a range of highly substituted tetrahydrofurans
报道了 γ-羟基/氨基烯烃与二芳基碘鎓三氟甲磺酸盐的有效铜催化分子间/分子内氧/氨基芳基化。在二氯甲烷中用三氟甲磺酸铜 (II) 简单激活这些芳基化剂会触发烯烃的平稳激活,同时被内部亲核试剂捕获,根据其性质产生一系列高度取代的四氢呋喃和吡咯烷。此外发现环化是立体特异性的,非对映异构烯烃产生环化产物的非对映异构体,并且可以扩展到氧炔基化。
