An enantioselective method for the synthesis of 1,2‐ anti ‐diols has been developed. A cyclometalated chiral‐at‐ruthenium complex catalyzes the asymmetric ring‐opening/cross‐metathesis of dioxygenated cyclobutenes, thus resulting in functionally rich synthetic building blocks. Syntheses of the insect pheromone (+)‐ endo ‐brevicomin and monosaccharide ribose demonstrate the synthetic utility of the 1,2‐ anti ‐diol fragments generated in the title reaction.
