Ni-catalyzed intermolecular allylic dearomatization reaction of β-naphthols with allylic alcohols was achieved. By utilizing Ni(cod)2 as a catalyst precursor, DPEphos as a ligand and 4 Å molecular sieves as additives, the dearomatization reaction of β-naphthols with aryl allylic alcohols proceeded smoothly under mild conditions, affording the desired β-naphthalenone products bearing a quaternary carbon
镍催化了β-萘与烯丙基醇的分子间烯丙基烯丙基脱芳香化反应。通过使用Ni(cod)2作为催化剂前体,DPEphos作为配体和4Å分子筛作为添加剂,β-萘酚与芳基烯丙基醇的脱芳香化反应在温和的条件下顺利进行,得到了所需的带有季碳中心,产率中等至良好,线性选择性优异。
