From the dipolar cycloaddition reactions of ketenes and aniles 2, the new azetidinones 3 and 4 were isolated. In addition the reaction between the nitrilimine 6 and cyclic olefins 7 gave new fused Δ2-pyrazolines 8, 9 and 10. The chemical behaviour and spectral data of the new compounds were determined.
