摘要

Functionalization of the α-and β-positions of readily available endocyclic enamine derivatives provides a convenient method for the formation of substituted pyrrolidines and piperidines. α-Alkoxy-β-iodopyrrolidines are formed by the electrophilic addition of iodine to the endocyclic enamine double bond of an N-substituted 2-pyrroline, and nucleophillic attack by an alcohol on the intermediate iodonium ion. The resultant α-alkoxy-β- ...
