  Efficient synthesis of seven-membered iminocyclitols from glycosylenamines

  摘要：

  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 C1-O bond. The overall yields are high.

  An easy route to seven-membered iminocyclitols from aldohexopyranosyl enamines

  摘要：

  A new stereocontrolled and high yielding synthesis of biologically active polyhydroxyperhydroazelpines is reported starting from easily available glycosylenamines (D-gluco, D-manno, and D-galacto configurations), which are transformed into 1,6-azaanhydropyranose derivatives. O- and N-Deprotection of the latter, followed by reduction with sodium cyanoborohydride, gives the target chiral iminocyclitols. The method is based on the capacity of the dialkoxycarbonylvinyl group to stabilize an amide ion, and the only limitation is the necessity for the starting glycosylenamine to have beta-D-configuration. The inhibitory activity of several intermediate iminocyclitols and aldopyranosylenamines on different alpha- and beta-glycosidases is also reported. (C) 2002 Published by Elsevier Science Ltd.
