The reaction of diisopropyl (Z)-(1-bromo-1-alkenyl)boronates readily obtainable, with organolithiums and bases takes place readily to give (E)-(1-organo-1-alkenyl)boronates, the cross-coupling of which with various organic halides proceeds smoothly in the presence of Pd-catalyst and base to afford stereodefined trisubstituted alkenes in good yields.
容易获得的二异丙基 (Z)-(1-溴-1-烯基) 硼酸酯与有机锂和碱的反应很容易得到 (E)-(1-有机-1-烯基) 硼酸酯,它与各种有机卤化物在钯催化剂和碱的存在下顺利进行,以良好的收率提供立体定义的三取代烯烃。
