In this critical review, the ring opening of non-activated 2-substituted aziridinesvia
intermediate aziridinium salts will be dealt with. Emphasis will be put on the relationship …

Due to their ready availability in chiral form, and propensity to undergo regio-and
stereoselective ring opening, aziridines have found widespread use in asymmetric …

Abstract Group 3–15 metal chlorides (Lewis acids) were classified on the basis of activity
and aldehyde‐and aldimine‐selectivity in an addition reaction of a silyl enol ether. Based on …

Several unsaturated sulfonamides underwent intramolecular aziridination when treated with
PhI (OAc) 2, MgO, and catalytic Rh2 (OAc) 4 to give bicyclic aziridines in excellent yield …

The discovery and development of a new Lewis acid system based on a complex formed
from niobium (V) methoxide and (R)-3, 3 '-bis (2-hydroxy-3-isopropylbenzyl)-1, 1 ' …

Aromatic electrophilic substitution reactions such as alkylation, acylation, benzoylation, and
sulfonylation were studied in the presence of a catalytic amount of Cu (OTf) 2 and Sn (OTf) 2 …

The kinetic resolution of 2‐aryl‐N‐tosylaziridines and the asymmetric desymmetrization of
meso‐N‐tosylaziridines by ring openings with various primary and secondary anilines, and …

Reaction of N-tosylaziridines with nitriles and carbonyls to produce imidazolines and
oxazolidines has been studied in the presence of a variety of Lewis acids. The reaction is …

An imidazole-based zwitterionic-salt, 4-(3-methylimidazolium) butane sulfonate (MBS), has
been found to be an efficient organocatalyst for aziridine ring-opening regioselectively by …

The ring-opening reactions of nonactivated aziridines with amine nucleophiles are efficiently
catalyzed by tris (pentafluorophenyl) borane leading to derivatives of trans-1, 2-diamines in …
