Axial Chirality
Axial Chirality — Chirality arising from restricted rotation around an axis rather than a stereocenter, relevant to constrained peptide and peptidomimetic design.
What Is Axial Chirality?
Axial chirality is chirality resulting from the non-planar arrangement of groups around an axis rather than a point (stereocenter). In peptide chemistry, axial chirality appears in binaphthyl-containing macrocyclic peptides, in atropisomeric peptide natural products, and in some constrained peptidomimetic scaffolds designed for conformational control.
Relevance
- Atropisomeric drugs: Rotation-restricted biaryl bonds create stable axial chirality that affects receptor binding
- Macrocyclic peptides: Ring strain in small macrocycles can create atropisomeric conformations
- Natural products: Vancomycin contains atropisomeric biaryl and biaryl ether bonds
