A regioselective and chemoselective method for catalytic synthesis of biologically interesting 5,6,7,8-tetrahydronaphthols by reduction of naphthols was described. The side aromatic hydrocarbons in naphthols were site-selectively reduced, using hydrosilanes in methanol, allowing for retaining functional phenol scaffolds intact. It presents a rare example of using low-cost and air-stable hydrosilane
描述了一种区域选择性和化学选择性方法,用于通过还原萘酚催化合成生物学上令人感兴趣的5,6,7,8-四氢萘酚。使用甲醇中的氢硅烷可选择性地还原萘酚中的侧链芳香烃,从而使功能性酚骨架保持完整。它提供了一个罕见的示例,该示例使用低成本且空气稳定的氢化硅烷在温和条件下催化还原未活化的芳烃。该反应是可扩展的,并且以高选择性进行,而没有形成1,2,3,4-四氢萘酚副产物,其可耐受敏感的官能团,例如溴化物,氯化物,氟化物,酮,酯和酰胺。
