A novel process is provided for the efficient preparation of an asymmetric compound of structural formula I:
employing dynamic kinetic resolution (DKR). The DKR process involves an enzymatic enantioselective amination reaction catalyzed by transaminases. The process can be used to manufacture key intermediates in the preparation of poly (ADP-ribose) polymerase (PARP) inhibitors which may be useful for the treatment of cancer.

Process development of the synthesis of the orally active poly(ADP-ribose)polymerase inhibitor niraparib is described. Two new asymmetric routes are reported, which converge on a high-yielding, regioselective, copper-catalyzed N-arylation of an indazole derivative as the late-stage fragment coupling step. Novel transaminase-mediated dynamic kinetic resolutions of racemic aldehyde surrogates provided
