Abstract
An efficient and highly enantioselective synthesis of florfenicol 1 was achieved with 37% overall yield starting from commercially available 4-methylthiobenzaldehyde. A key feature of the synthesis is the vanadium-catalyzed asymmetric epoxidation of allylic alcohol 5 with aq tert-butyl hydroperoxide to form (2 S,3 S)-epoxide 6.
