Reactions of N-Phosphorylated Aziridines with Dianions Derived from Ethyl Acetoacetate and 1,3-Diketones: New Route to Substituted Pyrrolines and Pyrrolidines

Abstract The nucleophilic ring-opening of N-(diethoxyphosphory)aziridines by the dianions derived from ethyl acetoacetate and 1,3-diketones has been studied. Acid-mediated cyclisation and dephosphorylation of the resulting products to a number of substituted pyrrolines and pyrrolidines has been also investigated.
