A novel gold‐catalyzed 6‐exo‐dig cycloisomerization of o‐propargylbiaryls has been developed that provides ready access to functionalized phenanthrenes in largely good to excellent yields. Notable features of this method are readily available starting materials, mild reaction conditions, and broad substrate scope.
已经开发了一种新型的金催化的邻炔丙基联芳基的6- exo - dig环异构化方法,该方法可以方便地获得官能化的菲,而且收率大体上很高。该方法的显着特征是易于获得的起始原料,温和的反应条件和广泛的底物范围。
