## Abstract The strained bridgehead olefins bicyclo [3.3.1]nonβ1βene (**1**), bicyclo [4.2.1 ]nonβ1(8)βene (**2**), and bicyclo [4.2.1]nonβ1βene (3), and the comparable monocyclic (__E__)β1βmethylcyclooctene (**4**) react with diphenylketene (**6**) to give a single cycloadduct **7**, **8**, **9**
In an excellent review' Lengyel and Sheehan have discussed the chemistry of alactams and pointed out that they appear to be unreactive as 1,3-dipoles in cycloaddition reactions. However, a-lactams possess a more than reasonable tendency to undergo ring opening by cleavage of the (sp3)C-N bond' in or
