Catalyst-free aziridination and unexpected homologation of aziridines from imines

Organic & Biomolecular Chemistry, 2010
Aziridination and unpredicted homologation reaction of N-sulfonylimines were achieved easily with a very simple, rapid and mild procedure through the use of diazomethane without the presence of any catalyst. The method represents an attractive alternative to metal-catalyzed processes.

Organocatalytic Asymmetric Aziridination of Enones

Angewandte Chemie International Edition, 2008
A primary amine derived from cinchona alkaloids as a salt with d-N-Boc phenylglycine (Boc = tert-butoxycarbonyl) is an efficient catalyst for the aziridination of α,β-unsaturated ketones. This method is effective with both linear and cyclic substrates, leading to chiral aziridines in high yield, with complete diastereoselectivity, and with very high ...

Chemistry of Carbohydrate Aziridines

2006
Publisher Summary This chapter discusses the chemistry of carbohydrate aziridines, with emphasis being placed on surveying preparative methods and ring-opening reactions. Carbohydrate aziridines or epimines are derivatives in which an aziridine ring is fused to a pyranose or furanose ring or to an exocyclic part of a carbohydrate molecule.

AZIRIDINES VIA ELECTROCHEMISTRY

Chemical & Engineering News Archive, 2002
A WIDE RANGE OF AZIRIdines—three-membered rings containing one nitrogen and two carbon atoms—are now accessible through an electrochemical process that requires no metal catalysts or oxidation reagents. Its organic chemist inventors at the University of Toronto believe the strategy will be adaptable to a wide range of chemical transformations ...
