Asymmetric Ring Opening

The catalytic asymmetric ring-opening transformations of aziridines represent an important strategy for the construction of various chiral nitrogen-containing molecular architectures. This short review covers the progress achieved in the catalytic asymmetric transformation of racemic aziridines, focusing on the catalytic strategies employed for each different type of such aziridines.1 Introduction2 Reaction of Racemic 2-Vinylaziridines3 Reaction of Racemic 2-Alkylaziridines3.1 Regiodivergent Parallel Kinetic Resolution3.2 Kinetic Resolution4 Reaction of Racemic 2-(Hetero)arylaziridines4.1 Kinetic Resolution4.2 Enantioconvergent Transformation5 Reaction of Racemic Donor–Acceptor-Type Aziridines6 Conclusion and Outlook
