Two sides of the same coin : Syn and anti 1,4‐diols have been synthesized through the regio‐ and diastereoselective Cu I ‐catalyzed boration of allylic epoxides (see scheme; pin=pinacolato, TES=triethylsilyl). In situ protection of the alcohol allows isolation of syn and anti 1,4‐silyloxyboronates. Monoprotected 1,4‐diols can be prepared by a one‐pot addition–protection–oxidation sequence.
