It is discovered that the diastereoselectivity of the Rh(I)-catalyzed Pauson–Khandcycloaddition of chiral enynes can be reversed to generate the trans diastereomer as the major product in the absence of a chelate phosphine ligand when the substrate contains an appropriate functional group capable of chelate coordination to the Rh(I) center. This expands the application of the Rh(I)-based catalytic
