Atropisomeric architectures, now as a characteristic of valuable chiral ligands and
organocatalysts, are increasingly encountered in modern materials and pharmacy. More
importantly, the Au-catalyzed diazo-alkyne carbocyclization has become a flexible
tool for facile construction of carbocyclic compounds, yet the preparation of axial
chirality via asymmetric gold-catalyzed intermolecular alkyne transformations is scarcely
reported. This mini-review aims to summarize the latest development of the axial atroposelective
synthesis via Au-catalyzed annulation of diazo-alkyne.
