We have succeeded in intramolecular nucleophilic substitution of the hydroxyl group in (S)-1-(alkylamino)-3,3,3-trifluoro-2-propanol. The reaction provides an optically pure (R)-1-benzyl-2-trifluoromethylaziridine in good yield from optically pure (S)-3-(benzylamino)-1,1,1-trifluoro-2-propanol, which was prepared from (S)-3,3,3-trifluoropropene oxide (75% ee).
