cycloaddition of C-benzoyl-N-phenylnitrone to electron-deficient alkynes. The 4- and 5-substituted cycloadducts react in different modes under the same conditions yielding enaminoderivatives, via a novel rearrangement process, and amines, aziridines and 1,3-oxazolines according to the substitution pattern.
