We report herein a highly straightforward strategy for the synthesis of a new axially chiral 3-arylindolizine scaffold via organocatalytic asymmetric arylation reactions of indolizines and p-quinone esters. Using the chiral phosphoric acid catalyst, a series of axially chiral 3-arylindolizines were accessed in good to excellent yields and atropo-enantioselectivities. This approach features a broad substrate scope, mild reaction conditions, good scalability, and facile derivatization. Moreover, preliminary investigations based on nonlinear effects and a thermal racemization study demonstrated the intrinsic pathway for the formation of axial chirality and its potential utility.
