Synthesis of Niraparib via Chemoenzymatic Dearomatization of Substituted Pyridines

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 6, 17 March 2026.
The synthesis of the PARP inhibitor Niraparib has been achieved via a chemoenzymatic dearomatization strategy. Chemical reduction combined with a one‐pot enzymatic cascade comprising an amine oxidase (AmOx) and an ene imine reductase (EneIRED) allowed for asymmetric reduction with high enantioselectivity.
