Nitrone has drawn great attention due to its wide applications as a 1,3-dipole in heterocyclic compounds synthesis and the bioactivities. With the special structure, nitrone can also be used as ligand in inorganic chemistry. Based on the current research,
Cycloaddition of acyclic nitrones with phenyl isocyanate: Synthesis and ring-opening reactions of 1,2,4-oxadiazolidin-5-ones

The cycloaddition of nitrones with unsubstituted or electron-donating substituents on the C-phenyl 1a,c,f with phenyl isocyanate proceeds smoothly for a short time with high yields to give the corresponding 1,2,4-oxadiazolidinone 2, and 1b,d,e with electron-withdrawing substituents gave the corresponding oxadiazolidinone in moderate yields after prolonged heating. Oxadiazolidinones 2a,c,f undergo diethylamine-induced fragmentation for a short time to give the corresponding Schiff bases, and oxadiazolidinones 2b,d,e remain unchanged in these conditions. Prolonged heating of 2d,e in the presence of diethylamine led to complex mixtures. In the case of 2b the corresponding amidine was the main product of the reaction.

Aromatic aldehydes 1 were reductively aminated to the corresponding secondary amines 2 using NaBH4 in methanol in good yields. Amines 2 were oxidized with H2O2-WO42- regioselectively to nitrones 3, the structures of which were easily determined by reacting them with hydroxylamine hydrochloride as well as by spectral means. The products of hydroxylaminolysis in ether proved to be the corresponding benzaldehyde oximes 4 and benzyl or methyl hydroxylamine hydrochlorides 5. Copyright Taylor & Francis, Inc.
A facile and new method for the synthesis of α-aryl-N-methylnitrones in solvent-free media using silica gel-NaOH

Substituted α-aryl-N-methylnitrones are prepared by the condensation reaction of N-methylhydroxylamine hydrochloride and benzaldehydes in solvent-free media using silica-gel-NaOH catalyst system. The yields are excellent regardless of the electron-donatin
An efficient and rapid chemoselective synthesis of α-Aryl-N-methylnitrones in dry media
Bigdeli,Nikje
, p. 1547 - 1549 (2007/10/03)
A simple, efficient, and eco-friendly procedure was developed for the condensation of N-methylhydroxylamine hydrochloride with benzaldehydes bearing electron-donating or electron-withdrawing substituents in the presence of powdered molecular sieves (3 A)
