Abstract

Abstract Different enantiopure terminal epoxides 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 enantiopure bromohydrins were obtained while using basic conditions (pH 9.5–10) epoxides were ...
