A formal [4 + 3]-annulation of vinyl arenes and diynyl propargyl esters is described. A mechanism involving cationic phosphinegold(I)-catalyzed tandem cyclopropanation/hydroarylation to produce the benzonorcaradiene products is proposed. In accord with this mechanism, the alkynyl cyclopropane can also be prepared with excellent regio- and diastereocontrol.

Copper-catalyzed reactions of terminal 1,3-diynes with electron-deficient azides to generate either 3-alkynyl or 2,3-dienyl imidamides and imidates are described. The selectivity depends on the diyne substituents and the nucleophile that reacts with the ketenimide intermediate generated from the corresponding triazole precursor. Reactions of 1,3-diynes containing a propargylic acetate afford [3]cumulenyl
