Fig. 1: Asymmetric catalytic approaches to N–N axial chirality and diastereodivergence.
From: Rhodium-catalyzed enantioselective and diastereodivergent access to diaxially chiral heterocycles
a State-of-the-art of construction of N–N axial chirality (rarely explored). b Two strategies of diastereodivergence. c Stereodivergent and asymmetic access to diaxes under condition control (this work).
