Metal-free oxidative esterification of benzylated monosaccharides

Methyl glyconates have been attracting considerable attention as intermediates for the preparation of aryl C-glycosides, polyphenolic products, aliphatic polyesters, SGLT2 inhibitors, antibiotics etc … In view of the interest in those compounds, we report herein our work on the synthesis of methyl glyconates using an oxidative esterification carried out by molecular iodine. This reaction is catalyzed by non-toxic K4Fe(CN)6 that releases a small amount of cyanide ion into the reaction mixture. Four benzylated carbohydrates which contain a hemiacetalic functional group have been tested successfully.
