construction of partially protected nonsymmetrical biaryldiols catalyzed by AgBF4 has been achieved. The approach facilitates the formation of two new aryl rings and the introduction of two hydroxyl groups (one free and one TBS-protected) via the o-NQM generation/semipinacol rearrangement cascade, featuring high atom- and step-economy to afford a diverse array of partially protected nonsymmetrical biaryldiols
已经实现了由AgBF 4催化的部分保护的不对称联芳基二醇的构建。该方法通过邻-NQM生成/ semipinacol重排级联促进了两个新的芳基环的形成和两个羟基的引入(一个游离基和一个TBS保护基),具有高原子经济性和阶梯经济性,可提供多种阵列温和条件下制备部分保护的不对称联芳基二醇。
