Gold-Catalyzed Deoxygenated Cyclization of <i>cis</i>-2,4-Dien-1-als with Regioselective Addition of Two Nucleophiles. One-Pot Synthesis of Highly Functionalized Cyclopentene Framework

Abstract

We report a new gold-catalyzed deoxygenated cyclization of cis-2,4-dien-1-als with external nucleophiles at ambient temperatures, which leads to a 1,4-double nucleophilic addition to the newly formed cyclopentene ring. The use of this cyclization is reflected not only by its compatibility with a wide scope of nucleophiles, but also by a facile construction of complex frameworks in diversified approaches.
