enantioenriched tertiary alcohols have been developed, and both the transition metal-catalyzed and the radical-based peripheral functionalization of tertiary alcohols have attracted intensive research interest in recent years. However, directly editing tetrasubstituted carbons remains challenging. Herein, we report a Pd-catalyzed migratory fluoroarylation reaction that converts tertiary alcohols to α-fluorinated
人们已经开发出许多对映体富集的叔醇的优雅的不对称合成方法,并且叔醇的过渡金属催化和基于自由基的外围官能化近年来引起了人们的广泛研究兴趣。然而,直接编辑四取代碳仍然具有挑战性。在此,我们报道了一种 Pd 催化的迁移氟芳基化反应,该反应将叔醇转化为 α-氟化叔烷基醚,收率良好至优异。沿着 C-O 键发生前所未有的 1,2-芳基/Pd IV共向重排,集成在 Pd II催化的多米诺骨牌过程中,是羟基和四取代碳双功能化的关键。该反应与多种官能团相容,生成叔烷基氟和烷基芳基醚官能团,并在四取代的立体中心处绝对构型发生反转。
