chemical production, although it is underutilized in organic synthesis. We have developed an intermolecular gold(I)-catalyzed alkyne/alkene reaction of o-allylphenols with acetylene gas that gives rise to chromanes by a stereospecific aryloxycyclization through the nucleophilic regioselective opening of cyclopropyl gold(I)-carbene intermediates. The synthetic application of this method was demonstrated in
乙炔气是化学生产的重要原料,但在有机合成中并未得到充分利用。我们开发了邻烯丙基酚与乙炔气体的分子间金(I)催化的炔/烯烃反应,通过环丙基金(I)-卡宾中间体的亲核区域选择性开放,通过立体特异性芳氧基环化产生色满。该方法的合成应用在天然产物拉帕胆的后期功能化中得到了证明。
