摘要：

While S(N)2 based desymmetrization of meso-epoxides has been extensively researched, the more general regioselective opening of cis-1,2 substituted epoxides via S(N)2 mechanism remains elusive. This short review outlines, how this limitation could be overcome by parting with S(N)2 and moving towards a radical-based mechanism. The development and refinement of the titanocene(III)-catalyzed regiodivergent epoxide opening (REO) is described.
