Efficient synthesis of seven-membered iminocyclitols from glycosylenamines

Seven membered iminocyclitols are synthesized in four steps from easily available glycosylenamines (D-gluco, D-galacto, and D-manno configurations) through 1,6-aza-anhydrosugar derivatives. These intermediates are transformed into 2-hydroxy- and 2-unsubstituted azepanes depending on the reactants used for the cleavage of the Cl-O bond. The overall yields are high.
