Preparation and ring-opening reactions of N-diphenylphosphinyl vinyl aziridines [PDF]
Beilstein Journal of Organic Chemistry, 2013 Predominantly (E)-N-diphenylphosphinyl vinyl aziridines are prepared by a reaction of N-diphenylphosphinyl imines with α-bromoallyllithium in the presence of freshly fused ZnCl2.

Organocatalyzed enantioselective desymmetrization of aziridines and epoxides
Beilstein Journal of Organic Chemistry, 2013 Enantioselective desymmetrization of meso-aziridines and meso-epoxides with various nucleophiles by organocatalysis has emerged as a cutting-edge approach in recent years.

Accessing Rare α-Heterocyclic Aziridines via Brønsted Acid-catalyzed Michael Addition/Annulation: Scope, Limitations, and Mechanism [PDF]
, 2023 We report an approach to the diastereoselective synthesis of 1,2-disubstituted heterocyclic aziridines. A Brønsted acid-catalyzed conjugate addition of anilines to trisubstituted heterocyclic chloroalkenes provides an intermediate 1,2-chloroamine ...

A Mild and Efficient Method for the Syntheses and Regioselective Ring-Opening of Aziridines
SynOpen, 2017 We have developed a new synthetic method for the synthesis of aziridines using Chloramine-T as an effective reagent in the presence of NH2OH·HCl and NaIO4.

Coupling of 1-alkyl-2-(bromomethyl)aziridines with heteroatom-centered nucleophiles towards 2-[(heteroatom)methyl]aziridines [PDF]
ARKIVOC, 2007 The reactivity of 1-alkyl-2-(bromomethyl)aziridines with respect to different types of oxygen-, nitrogen- and sulphur-centered nucleophiles has been evaluated, pointing to the conclusion that these substrates can be applied successfully as synthetic ...

Hard to make space: improving access to privileged pharmacophores [PDF]
Limited examples of the successful ring expansion of aziridines with sulfonium ylides to generate azetidines are known, but typically result in functional groups on azetidine that are not broadly useful for downstream chemistry.
