Reaction of Azomethine N-Oxides. 6. Spectroscopic Study of Lewis Acid Catalyzed Reactions of Nitrones with N-Phenylmaleimide

The effect of the Lewis acid AlCl3 on the reactivity and stereoselectivity of the 1,3-dipolar cycloaddition reactions of some azomethine N-oxides with N-phenylmaleimide in benzene at room temperature has been spectroscopically investigated.Decrease of the reactivity and increase of the stereoselectivity of the cycloaddition reactions are observed.

1,3-Dipolar Cycloaddition Reactions between some C-Aryl Nitrogen Oxides with Electron-deficient Dipolarophils

Both C-(2-methylphenyl)-N-phenyl and C-(3-methylphenyl)-N-phenyl nitrones (1a, b) reacted with N-phenylmaleinimide and fumaronitrile to give the normal primary cycloadducts.The reaction of the two nitrones (1a, b) with 4-phenyl-1,2,4-triazoline-3,5-dione and diacetylacetylene afforded rearrangement products.The unexpected 1,3,4-oxadiazolidin-2-ones were isolated from reaction with phenylisocyanate.In contrast, tetracyanoethylene forms charge-transfer complexes with both nitrones instead of cycloaddition products.The structural elucidation of the reaction products was made on the bases of the elemental analysis as well as i.r. and 1H-n.m.r. spectral data.
