Abstract

Aldimines, generated in situ from arylamines and aryl aldehydes, undergo smooth cycloaddition with cyclopropane-1,1-dicarboxylate in the presence of the cerium(III) chloride heptahydrate-lithium iodide reagent system in refluxing acetonitrile under neutral conditions to produce the corresponding N-arylpyrrolidines in good yields with high selectivity.
