Attempted Beckmann rearrangement of dehydronorcamphor oxime resulted in Beckmann fragmentation and dimerization of the intermediate cyanomethylcyclopenta-1,3-diene isomers.The dienes can be trapped by N-phenylmaleimide to yield two isomeric crystalline adducts.When the olefin in dehydronorcamphor oxime is effectively blocked, Beckmann rearrangement takes place to provide stereochemically pure bicyclic lactam.
