A Conceptually New and Straightforward Method for the One-pot Transformation of Alcohols into Amines
Abstract A conceptually new amination method of alcohols has been developed using α-hydroxy esters as substrates and N-phenyl BIS-trifluoromethanesulfonimide (PhNTf 2 ) as a test reagent. Playing two roles at once, PhNTf 2 activates the hydroxyl group as a highly reactive triflate intermediate and i...

Zusammenfassung: | Abstract
A conceptually new amination method of alcohols has been developed using α-hydroxy esters as substrates and N-phenyl BIS-trifluoromethanesulfonimide (PhNTf
2
) as a test reagent. Playing two roles at once, PhNTf
2
activates the hydroxyl group as a highly reactive triflate intermediate and introduces the amino functionality through an in situ nucleophilic substitution by the anionic residue PhTfN
-
. Two complementary procedures (methods A and B herein) have been developed, the latter permitting reaction of substrates with unstable alcoxides. |
