Biphenyls allenes and spiranes
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.
