The synthesis of 1‐vinyl‐, 3‐vinyl‐ and 3‐alkynylcyclobutenes has been achieved by a gold(I)‐catalyzed [2+2] cycloadditionreaction. One‐pot transformations of the versatile cyclobutenes render cyclopentenes, 2,3‐dihydrofurans, polycyclic skeletons and beyond.

The gold(I)-catalyzedintermolecular reaction of terminal alkynes with alkenes leads to cyclobutenes. The use of sterically hindered cationic Au(I) complexes as catalysts is key for the success of this reaction.
