Halohydrin dehalogenases (HHDHs) offer a biocatalytic route to chiral azido alcohols and epoxides. In previous work, we reported an (R)-enantioselective azidolysis of fluorinated aromatic epoxides by HheC from Agrobacterium radiobacter AD1. Herein, we employed the HheA2-N178A variant, displaying high (S)-enantioselectivity, for the synthesis of a wide range of fluoroaromatic azido alcohols. Initially, we assayed 14 fluorinated styrene oxide derivatives and found high enantioselectivity in reactions (E up to 200), regardless of the substituent position. Biotransformations upscaled to 100 mM substrate concentration were carried out in a two-phase system, and the products were isolated in excellent enantiomeric purity (93 – >99% ee). Additionally, the structure of HheA2-N178A enzyme was determined.
