Rhenium‐Catalyzed Construction of Polycyclic Hydrocarbon Frameworks by a Unique Cyclization of 1,n‐Diynes Initiated by 1,1‐Difunctionalization with Carbon Nucleophiles

A regioselective cyclization of 1,n‐diynes under rhenium catalysis was developed on the basis of a rare type of 1,1‐difunctionalization of terminal alkynes with carbon nucleophiles, followed by sequential addition reactions of the resulting alkenylrhenium species. The reaction provides an efficient...
