Abstract
Enantiomerically pure disubstituted pyrrolidines, recently synthesized from commercially available enantiomerically pure β-aminoalcohol, were used as starting materials to synthesize enantiomerically pure hexahydro-1 H-pyrrolizines and octahydroindolizine through a cyclization reaction promoted by N-(phenylseleno)phthalimide. Similarly, starting from enantiopure 5-(hydroxymethyl)pyrrolidin-2-ones, enantiopure hexahydro-3 H-pyrrolizin-3-ones were obtained.
