The palladium-catalyzed one-pot synthesis of 2,3-deoxy-3-keto aryl C-glycosides is achieved from glycals and anilines in the presence of tert-butyl nitrite and aqueous HBF 4 under mild conditions. This one-pot method stereospecifically provides α-and β-Aryl glycosides (≥19:1 by NMR) in good yields at room temperature. The configuration at the C-3 position in the glycal determines the anomeric selectivity (i.e., α or β) of the desired products.

Arylbis(arylthio)sulfonium salts have been used to activate glycals towards nucleophilic addition to form principally 2-deoxy-β-glycosides. This method was applied to the synthesis of the 2-(methylphenylthio)-2'-phenylthio derivative (22) of methyl O-(4-O

Medermycin has been first synthesized from D-rhamnose derivatives and comfirmed to be identical with lactoquinomycin.
SYNTHESIS OF THE DISACCHARIDE C-D FRAGMENT FOUND IN EVERNINOMICIN-C AND -D, AVALAMYCIN-A AND -C, AND CURAMYCIN-A: STEREOCHEMISTRY AT THE SPIRO-ORTHOLACTONE CENTER

, p. 1105 - 1108 (2007/10/02)
The two isomers at the spiro-ortholactone center of the disaccharide C-D fragment of orthosomycins have been synthesized.Their mild acidic hydrolysis was under stereoelectronic control with each isomer leading to only one ester.It is therefore possible, f
