1,2-bimetallic reagents are useful motifs in synthetic chemistry. Although syn-1,2-bimetallic compounds can be prepared by alkene dimetallation, anti-1,2-bimetallics are still rare. The stereospecific 1,2-metallate shift that occurs during conjunctive cross-coupling is shown to enable a practical and modular approach to the catalytic synthesis of enantioenriched anti-1,2-borosilanes. In addition to
手性1,2-双金属试剂是合成化学中有用的基序。尽管可以通过烯烃的双金属化制备顺式1,2-双金属化合物,但反式1,2-双金属化合物仍然很少。在立体交叉偶联过程中发生的立体有规的1,2-金属盐移位显示出可以实现一种实用且模块化的方法来催化合成对映体富集的抗1,2-硼硅烷。除反应开发外,还研究了抗1,2-硼硅烷的合成用途,包括在抗1,2-二醇和抗1,2-氨基醇的合成中的应用。
