The direct borylation of disubstituted alkenes is reported. These conditions allow for the conversion of a variety 1,1- and 1,2-disubstituted alkenes to trisubstituted alkenyl boronic esters with outstanding yields and excellent E/Z selectivities. The utility of this reaction has been demonstrated with several downstream functionalization reactions, which allow access to diverse, stereodefined, functionalized
报道了二取代烯烃的直接硼基化。这些条件允许将各种 1,1-和 1,2-二取代烯烃转化为三取代烯基硼酸酯,具有出色的产率和优异的E / Z选择性。该反应的实用性已通过几个下游官能化反应得到证明,这些反应允许获得多种立体定义的官能化烯烃。机理研究与硼基-赫克途径一致。
