Reactions of Cyclic Diazoamides:Convenient Synthesis of Dispirocyclic Cyclopropane Systems

Abstract
Rhodium(II) acetate catalyzed intermolecular cyclopropanationreactions of cyclic diazoamides with exocyclic olefins are describedto furnish an assortment of stable strained dispirocyclic cyclopropanesystems in good yields under mild experimental conditions.
