  • Modular, Catalytic Enantioselective Construction of Quaternary Carbon Stereocenters by Sequential Cross-Coupling Reactions
    作者:Bowman Potter、Emma K. Edelstein、James P. Morken
    DOI:10.1021/acs.orglett.6b01580
    日期:2016.7.1
    chiral γ,γ-disubstituted allylboronates in the presence of RuPhos ligand occurs with high regioselectivity and enantiospecificity, furnishing nonracemic compounds with quaternary centers. Mechanistic experiments suggest that the reaction occurs by transmetalation with allyl migration, followed by rapid reductive elimination.
    在 RuPhos 配体存在下,与手性 γ,γ-二取代烯丙基硼酸酯的催化 Suzuki-Miyaura 交叉偶联发生具有高区域选择性和对映专一性,提供具有四级中心的非外消旋化合物。机理实验表明,该反应通过金属转移和烯丙基迁移发生,然后快速还原消除。
