The development of methods for the asymmetric synthesis of N-N axial chirality remains elusive and challenging. Here, we disclose a method for the construction of N-N axially chiral pyrrolyl-oxoisoindolins along with central chirality via the isothiourea (ITU)-catalyzed acylative dynamic kinetic resolution (DKR). Axial chirality was introduced into the acylative DKR of hemiaminals for the first time. This protocol features mild conditions with excellent yields and enantioselectivities.
