Axially chiral architectures exist widely in natural products, biologically relevant molecules, chiral ligands and catalysts as well as functional materials. Therefore, catalytic asymmetric synthesis of atropisomers has become one of the most fast‐growing fields in the community of chemistry and rapid advances have occurred. Among different methods reported, the organocatalytic atroposelective dynamic kinetic resolution (DKR) involving ring manipulations stands out as a cutting‐edge technology to construct axial chirality from the point of atom/step economy. In this DKR strategy, the configurational lability of starting materials originates from chirally‐labile ring structure of cyclic substrates/intermediates or transient ring formation through noncovalent interactions from acyclic substrates. The two atropisomers of starting material are in equilibrium in the reaction medium, ensuring the constant transformation of the less reactive atropisomer into the more reactive one, and then to a single enantiopure product in the presence of an appropriate organocatalyst. This review summarizes recent advancements on this topic, including their scopes, limitations, mechanisms, applications and provides some insights into further developments.
