A Novel Approach to Aminocyclitol Analogues from Azidotrideoxyhex-5-enopyranosides
Pelyvas, Istvan,Sztaricskai, Ferenc,Bognar, Rezsoe
, p. 104 - 105 (2007/10/02)
Application of the Ferrier's carbocyclic ring closure to methyl 3-azido-2,3,6-trideoxyhex-5-enopyranosides leads to cyclitol derivatives (3) and (5) suitable for the convenient synthesis of 1,3-diaminocyclitol-type aminoglycoside antibiotic analogues.
