Pentacyclic isoxazolines were obtained by the cycloaddition of benzonitrile oxide to norbornene‐azetidinone‐fused 3,1‐oxazines. The constitutions of two of the isomers obtained, and the configurations and conformations of all products, were determined by means of 1 H and 13 C NMR spectroscopy and DNOE experiments.
