enantioselective reaction has been developed for the construction of axially chiral arylpyrazole skeletons with phosphorus unit. The reaction proceeds through a sequential Huisgen-type cycloaddition/aromatization process with central-to-axial chirality conversion using a dipeptide-phosphonium salt catalyst. Arylpyrazole-based atropisomeric phosphorus compounds are obtained in high yields with excellent enantioselectivities
