reaction of substituted anilines have been developed using chiral phosphoric acid catalysis, enabling access to axially chiral diarylamines. The key feature of this strategy is that the “NO2···H–N” hydrogen bond was successfully introduced into acyclic diaryl secondary amines, which contain two potential contiguous atropisomeric C–N axes, to stabilize one of the planar axial conformations. This methodology
