Notizen:
An eight-step synthetic sequence led from the known D-xylo-pentodialdose 8 to imidazo-L-xylo-piperidinose 15, the key steps being the build-up of imidazole compound 12 by a van Leusen methodology and the intramolecular SN2 ring closure of the O-triflated benzylidene derivative 13. xylo-Piperidinose 15 appears in a half-chair conformation like the oxocarbonium ions which are the postulated intermediates in the glycoprocessing of the pyranose polysaccharides. This bicyclic azasugar should be a glycosidase inhibitor.
