The phosphoric acid catalyzeddirect arylation of 2-naphthylamines with iminoquinones enables the atroposelective synthesis of axiallychiral biaryl amino alcohols. Many functional groups are tolerated in this reaction, and it is a rare example of 2-naphthylamines acting as nucleophiles in an organocatalytic enantioselective transformation.

atroposelective strategy for accessing enantioenriched axially chiral IAN analogues was developed for the first time. A class of novel atropisomeric C2‐arylquinoline skeletons were synthesized with high enantiocontrol via chiral phosphoric‐acid‐catalyzed heteroannulation of in situ generated vinylidene ortho‐quinone methide (VQM) intermediates with ortho‐aminophenones. The strategy tolerated a broad
