A Pt−Ni alloy nanocatalyst is developed for the diastereoselective directed hydrogenation of tetrasubstituted olefins in a cyclopentene scaffold. For this substrate class, established homogeneous catalysts generate hydrogenolysis side products, and commercial heterogeneous catalysts are not stereoselective. Uniform alloying of the noble metal and base metal combined with high catalyst dispersion is
