Nitrones and oxaziridines. VII. Cycloaddition reactions of nitrones with carbon disulphide
Australian Journal of Chemistry, 1973The cyclic aldo nitrones (3)-(5) undergo cycloaddition reactions with carbon disulphide to yield the related thiolactams (6)-(8), presumably via intermediate 1,4,2-oxathiazolidine-5-thiones, which could not be isolated or detected. N-(Benzylidene)-methylamine N-oxide undergoes a similar conversion into the related thioamide, but the reaction is not ...

Nitrones. Part V. The reaction of a cyclic nitrone with diethyl malonate
Journal of the Chemical Society C: Organic, 1967The cyclic nitrone, 5,5-dimethyl-1-pyrroline 1-oxide, has been shown to react with diethyl malonate, under basic conditions, to yield 4-ethoxycarbonyl-8,8-dimethyl-2-oxa-1-azabicyclo[3,3,0]octan-3-one. Reduction of this product with lithium aluminium hydride yielded 2-(1-hydroxy-5,5-dimethylpyrrolidin-2-yl)propane-1,3-diol, while thermal degradation ...

Tetrahedron, 1968
Abstract The mass spectra of a series of nitrones are reported and discussed. All spectra contain molecular ions, and the majority of fragment ions owe their genesis to skeletal-reorganization of the molecular ion. Fragmentation modes have been substantiated by high-resolution data and appropriate metastable ions. Deuterium labelling has been used to
