The Lewis acid-catalyzed regioselective azidolysis of 2,3-epoxy amines has been investigated. The results obtained demonstrated that using TMSN3 as a source of azide, the appropriate choice of Lewis acid allowed to direct the regiochemistry of the ring opening.

Abstract
The Lewis acid-catalyzed regioselective azidolysis of 2,3-epoxy amines has been investigated. The results obtained demonstrated that using TMSN3 as a source of azide, the appropriate choice of Lewis acid allowed to direct the regiochemistry of the ring opening. The present methodologies provide a powerful tool in organic synthesis for the preparation of diaminoalcohol moieties.File in questo prodotto:
