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.
