The confusion that can arise from an unsuspected Wagner-Meerwein rearrangement is amplified in many of the reactions of bicyclic molecules because the rearranged products may retain the same bicyclic structure and differ from the non-arranged products only in the position of substituents. The commercial conversion of camphene to isobornyl acetate is a classic example of a reaction of a bicyclic molecule proceeding with a Wagner-Meerwein rearrangement.
