Alkyl phenyl selenides derived from the benzeneselenenyl chloride induced
cyclization of N-protected pent-4-enylamines can be
converted in good yield into the corresponding 2-hydroxymethyl- or 2-
alkoxymethyl-substituted pyrrolidines by oxidation to the corresponding
selenone, followed by reaction with water (or hydroxide) or with the
corresponding alcohol. Details of the reactions and possible mechanisms for
the substitution are discussed.
