It is shown how the simple titanocene(III)-catalyzed reductive opening of epoxides
has developed from a highly selective desymmetrizing opening of meso-epoxides. The combination of the origins of regioselectivity with atom-economic catalysis
in single electron steps results in a highly selective regiodivergent epoxide opening
(REO).
