The enantioselectivesynthesis of α‐thiocarboxylic acids by biocatalytic dynamic kinetic resolution (DKR) of nitrile precursors exploiting nitrilase enzymes is described. A panel of 35 nitrilase biocatalysts were screened and enzymes Nit27 and Nit34 were found to catalyse the DKR of racemic α‐thionitriles under mild conditions, affording the corresponding carboxylic acids with high conversions and
