  • Title: Biomimetic Hydrogenation Catalyzed by a Manganese Model of [Fe]-Hydrogenase.
    Author: Pan HJ, Hu X.
    Journal: Angew Chem Int Ed Engl; 2020 Mar 16; 59(12):4942-4946. PubMed ID: 31820844.
    Abstract:
    [Fe]-hydrogenase is an efficient biological hydrogenation catalyst. Despite intense research, Fe complexes mimicking the active site of [Fe]-hydrogenase have not achieved turnovers in hydrogenation reactions. Herein, we describe the design and development of a manganese(I) mimic of [Fe]-hydrogenase. This complex exhibits the highest activity and broadest scope in catalytic hydrogenation among known mimics. Thanks to its biomimetic nature, the complex exhibits unique activity in the hydrogenation of compounds analogous to methenyl-H4 MPT+ , the natural substrate of [Fe]-hydrogenase. This activity enables asymmetric relay hydrogenation of benzoxazinones and benzoxazines, involving the hydrogenation of a chiral hydride transfer agent using our catalyst coupled to Lewis acid-catalyzed hydride transfer from this agent to the substrates.
