simple silver salt (AgOAc)-catalyzed anti-Markovnikov-selective hydroboration of alkenes, 1,3-dienes, and alkynes with pinacolborane (HBpin) has been described. This strategy provides an efficient and practical method to access various alkyl-, allyl-, and (E)-alkenylboronate esters in good to excellent yields with regio- and stereoselectivity under ligand- and base-free conditions.
已经描述了简单的银盐(AgOAc)催化的频哪醇硼烷(HBpin)对烯烃,1,3-二烯和炔烃进行的反马氏化学选择性硼氢化反应。该策略提供了一种有效且实用的方法,可在无配体和无碱条件下,以区域和立体选择性,以良好或优异的收率获得各种烷基,烯丙基和(E)-烯基硼酸酯。
