WebConfigurational Nomenclature of Chiral Biphenyls • Selection rules for axial chirality has been introduced in case of atropisomers. The absolute nomenclature of axially chiral biphenyls, on the basis of axial chirality, is determined by the same method as in the case of axially chiral allenes, spiranes, etc. WebFurthermore, some optically active molecules; like allenes, biphenyls, and spiranes; can have axial as well as helical chirality. The route to do so is the same except for the fact that such molecules must be viewed along the chiral axis first, and priorities are assigned separately at both ends.
