assay substrates that incorporate structural variations, an efficient modular synthetic route was developed. This includes racemate resolution by lipase‐catalyzed transacylation to furnish enantiomerically pure (R)‐ and (S)‐configured amines. The latter are instrumental for the rapid enantioselectivity typing of ω‐transaminases. This method was used to characterize two novel (S)‐selective taurine‐pyruvate
