本文报道了铂催化的二硼频哪醇酯对简单单取代烯烃的不对称加成反应。该反应在容易获得的手性亚膦酸酯配体的存在下发生,并且对各种末端烯烃底物有效。重要的是,该反应可以在催化剂负载量仅为1摩尔% Pt的情况下进行。虽然中间体1,2-双(硼酸酯)酯的氧化提供手性1,2-二醇作为反应产物,但是中间体也可以进行同系化/氧化以提供手性1,4-二醇作为反应产物。
The Pt-catalyzed enantioselective addition of bis(pinacolato)diboron to simple monosubstituted alkenes is described. This reaction occurs in the presence of a readily available chiral phosphonite ligand and is effective with a variety of terminal alkene substrates. Importantly, the reaction can operate with catalyst loadings of only 1 mol% Pt. While oxidation of the intermediate 1,2-bis(boronate) ester provides the chiral 1,2-diol as the reaction product, the intermediate may also be subjected to homologation/oxidation to furnish a chiral 1,4-diol as the reaction product.
