    日期:2013.12
    Catalytic (DHQD)2PHAL as modified by added benzoic acid, is an off-the-shelf catalyst-additive combination for effecting catalytic asymmetric bromolactonization reactions. This combination delivers bromolactones with asymmetric induction at a comparable level to bespoke catalysts previously optimized for particular substrate classes.

  • (Salen)Mn(III)-Catalyzed Enantioselective Intramolecular Haloamination of Alkenes through Chiral Aziridinium Ion Ring-Opening Sequence
    作者:Hui Sun、Huijian Shang、Bin Cui
    DOI:10.1021/acscatal.2c02223
    日期:2022.6.17
    Asymmetric catalysis with a chiral (Salen)Mn(III) complex is applied successfully to highly enantioselective intramolecular haloamination reactions of alkenes through a chiral aziridinium ion ring-opening sequence. Computational and experimental studies suggested that the C5–C6 bond polarization has a major effect on the regioselectivity of the chiral aziridines ring intermediate, and steric hindrance
