Gold catalysis enables an efficient intermolecular [2+2] cycloaddition between two different types of chloroalkynes and unactivated alkenes. Monosubstituted unactivated alkenes can be converted with excellent regioselectivities. With 1,2-disubstituted unactivated alkenes, the reaction is largely stereospecific.
