  • Chiral 1,3-diarylimidazolium salt carbene precursor, synthesis method therefor, metal salt compound and application thereof
    Patent number: 11345665
    Abstract: Chiral 1, 3-diarylimidazole salt carbene precursors, their methods of preparation, particularly transition metal complexes and their use in chemical synthesis are provided. In particular, an air and moisture stable chiral 1, 3-diarylimidazole carbene precursor Cu (I) complex has been prepared and applied to highly regio- and enantioselective Markovnikov hydroboration of unactivated terminal alkenes to form chiral boronic esters. Moreover, these new chiral NHCs can be potentially applied in various metal-catalyzed asymmetric transformations.
    Type: Grant
    Filed: November 15, 2018
    Date of Patent: May 31, 2022
    Assignee: Shanghai Institute of Organic Chemistry, Chinese Academy of Sciences
    Inventors: Shiliang Shi, Yuan Cai, Xintuo Yang, Feng Li
