Aziridines (azacyclopropanes) constitute the well-known class of heterocyclic compounds. The studies on synthesis and reactivity of aziridines have drawn tremendous interest of organic chemists. The main feature of interest in the chemistry of this molecule is the ring-strain associated with it.Aziridines are attractive and versatile building blocks in organic synthesis and medicinal chemistry because they allow convenient access to useful nitrogen-containing biologically active compounds.SYNTHESIS OF IMIDAZOLINES FROM AZIRIDINES By Michael Robert Kuszpit The majority of the work in this thesis presents a new method to syntheisize imidazolines from both chiral and racemic aziridines. The purpose of synthesizing such heterocycles was for there known biological activity. Previous research in the Tepe group has.

The organocatalytic ring-opening polymerization of N-tosyl aziridines by an N-heterocyclic. in molecular chemistry.1,2 Polymer synthesis has also greatly benefited from the potential of NHCs, providing a straightforward and metal-free synthetic strategy to a wide range of polymers. 3.
Introduction Aziridines are interesting synthetic building blocks for the construction of complex nitrogen containing compounds. When activated by a N-tosyl group, they are especially reactive towards nucleophilic ring opening and provide an easy access to a wide variety of alkaloid structures ( 1 ).
Ring Opening Reactions of N-Tosyl Aziridines. One-pot synthesis of various aziridines was also successfully carried out without isolation of the intermediate 2 References 1) J. A. Deyrup, in “Small Ring Heterocycles,” ed. by A. Hassner, John Wiley and Sons, New York (1983), Part 1, p 1.
TY - JOUR. T1 - alpha-lithiation-rearrangement of N-toluenesulfonyl aziridines with sec-butyllithium and (-)-sparteine: opposite sense of asymmetric induction to epoxides.
Synthesis. There are several syntheses of aziridines (aziridination). Cyclization of haloamines and amino alcohols. An amine functional group displaces the adjacent halide in an intramolecular nucleophilic substitution reaction to generate an aziridine.
Synthetic Applications of N-H Aziridine Containing Compounds Shannon Marie Decker Master of Science Department of Chemistry University of Toronto 2010 Abstract Unprotected N-H aziridine aldehydes are surprisingly stable compounds which can undergo reactions in the absence of protecting groups.

Synthesis. Several routes have been developed for the syntheses of aziridines (aziridination). Cyclization of haloamines and amino alcohols. An amine functional group displaces the adjacent halide in an intramolecular nucleophilic substitution reaction to generate an aziridine. The parent aziridine is produced industrially from aminoethanol via two related routes.

A variety of N-tosyl aziridines undergo ring opening with indium trihalides in acetonitrile at ambient temperature to afford the corresponding haloamines in excellent yields with high regioselectivity.
Sodeoka and Kawamura et al. have recently reported 1-tosyl-2-(2,2,2-trifluoroethyl)aziridine (1), which is utilized in the synthesis of trifluoroalkylamine derivatives. 1 reacts with various carbon and nitrogen nucleophiles to provide ring-opening adducts with high regioselectivity and in high yields.
