Nonactivated 2-(thiocyanatomethyl)aziridines with diverse substitution patterns were deployed as substrates to effect a LiAlH4-promoted thia-aza-Paynerearrangement to provide access to functionalized2-(aminomethyl)thiiranes in good to excellent yields (78–94 %). The developed strategy involved hydride reduction of the thiocyanato moiety followed by intramolecular aziridine ring opening. Subsequent
