Chemoenzymatic synthesis: The preparation of florfenicol features the use of enzymatic dynamic reductive kinetic resolution (DYRKR) to establish the two stereocenters of the cis‐1,2‐amino alcohol intermediate with >99 % ee and a diastereomeric ratio (dr) of 99 %. The treatment of aziridines and cyclic sulfates with Et3N‐3HF was used to introduce the fluorine atom with high regioselectivity.
