The enantioselective syntheses of axially chiral heterobiaryls were accomplished through the aromatic electrophilic halogenation of 3‐(quinolin‐8‐yl)phenols with bifunctional organocatalysts that control the molecular conformations during successive halogenations. Axially chiral quinoline derivatives, which have rarely been synthesized in an enantioselective catalytic manner, were afforded in moderate‐to‐good

生物很少以对映选择性催化方式合成,通过
溴化反应可得到中等至良好的对映选择性,类似的方案也可实现对映选择性
碘化。此外,这种催化反应允许通过使用单邻位取代的底物进行对映选择性控制,从而实现了高对映选择性下带有两个不同卤素基团的8-芳基
