The invention is directed to an improved process for the preparation of spirocyclic lactams which utilizes diiodides in the spiro alkylation of lactams N-substituted with a tertiary amine group. The resultant spirocyclic lactams are useful in the production of various substituted azaspiranes which are useful as immunomodulatory agents.
