Total syntheses of glucosidase inhibitors, cyclophellitols

A β-D-glucosidase inhibitor, cyclophellitol heptane-2,3,4-triol, 1> and its epoxide diastereomer, 1,6-epicyclophellitol (2) have been synthesized by using an intramolecular -cycloaddition of a n

Studies on the 6-homologation of β-D-idopyranosides

β-D-Idopyranosides are interesting sugars because of their unusual conformational flexibility in the pyranosyl ring, and also their β-1,2-cis-anomeric configuration. Here we report our studies of the regioselective opening of 4,6-O-benzylidene-protected β-D-idopyranosides under reducing conditions, and the subsequent 6-homologation via Swern oxidation and Wittig olefination to afford a 6,7-dideoxy-β-D-ido-hept-6-enopyranoside. This olefination product was found to adopt predominantly 1C4 conformation in solution by NMR experiments, which places the vinyl group at a more sterically hindered axial position and creates difficulty in subsequent hydroborations.

Enantiospecific total synthesis of a β-glucosidase inhibitor, cyclophellitol

Cyclophellitol has been synthesized from L-glucose through an intramolecular cycloaddition of a nitrile oxide derived from an oxime.
