The hydrolytic ring opening of epoxides is an important biosynthetic transformation and is also applied industrially. We report the first organocatalytic variant of this reaction, exploiting our recently discovered activation of carboxylic acids with chiral phosphoric acids via heterodimerization. The methodology mimics the enzymatic mechanism, which involves an enzyme‐bound carboxylate nucleophile

The chiral Co(salen) complex 3 is an effective catalyst for the asymmetric ring-opening of meso epoxides with benzoic acid. Enantioselectivities of 55–93% were obtained with a range of substrates.
