Abstract
1,3-Dipolar cycloaddition of N-aryl-C-phenylnitrones to bicyclopropylidene and subsequent thermal rearrangement afforded mixtures of spirocyclopropane -annelated tetrahydropyridones 12 and benzoazocinones 13 in good overall is olated yields (61-82%). The effect of para-substituents on the N-aryl ring has been found to be marginal.
