  • Asymmetric Hydrogenation of Cyclic Imines of Benzoazepines and Benzodiazepines with Chiral, Cationic Ruthenium-Diamine Catalysts
    作者:Zhusheng Yang、Ziyuan Ding、Fei Chen、Yan-Mei He、Nianfa Yang、Qing-Hua Fan
    DOI:10.1002/ejoc.201700236
    日期:2017.4.10
    The title hydrogenation reaction is achieved in the presence of phosphine‐free, chiral, cationic ruthenium–diamine complexes and provides facile access to various chiral seven‐membered N‐containing heterocycles. A reversal of enantioselectivity is observed simply by changing the achiral counteranion of the catalyst.

    A new preparation of 1,5-benzodiazepine derivatives has been achieved in good to excellent yields by the condensation of o-phenylenediamine with a variety of ketones employing nano-γ-Fe2O3–SO3H as catalyst under microwave irradiation and solvent-free conditions. Recyclable nano-γ-Fe2O3–SO3H provided high reactivity and was easily separated from the reaction mixture by using an external magnet. The advantages offered by this method are based on the principles of ‘green chemistry’: a facile and rapid reaction, no solvent, easy separation of products and good to excellent yields..
