The gold(I)-catalyzed intramolecular cycloisomerization of furan/ynes bearing a silyloxy or allyloxy group has been developed, which provides a highly efficient access to protected 1-naphthol derivatives with enal or enone moiety. The method offers several advantages such as high stereoselectivities, mild reaction conditions, and easily accessible starting materials. In addition, the naphthyl products
已经开发了具有甲硅烷基氧基或烯丙氧基的呋喃/炔的金(I)催化的分子内环异构化,其提供了对具有烯丙基或烯酮部分的被保护的1-萘酚衍生物的高效访问。该方法具有许多优点,例如高的立体选择性,温和的反应条件和易于获得的起始原料。另外,可以通过一锅法将萘基产物进一步转化为重要的苯并香豆素。
