Abstract
A gold-catalyzed intramolecular cycloisomerization of α-yne-furans 1 is described in this contribution. A variety of cyclic α,β-unsaturated aldehyde or ketone derivatives and nitrogen-containing tricyclic adducts were obtained selectively in moderate to excellent yields under mild conditions by varying the substituents on the standard substrates.
摘要
本文介绍了一种金催化的α-炔基呋喃1的分子内环异构化反应。通过改变标准底物上的取代基，在温和条件下以中等至优异的产率选择性地获得了多种环状α,β-不饱和醛或酮衍生物以及含氮三环加合物。
