Different enantiopureterminalepoxides or bromohydrins have chemoselectively been synthesised in one‐pot starting from the corresponding α‐bromo ketones through alcohol dehydrogenase (ADH)‐catalysed processes adding an organic co‐solvent and tuning appropriately the medium pH and the temperature. Thus, at neutral pH enantiopurebromohydrins were obtained while using basic conditions (pH 9.5–10) epoxides
