Convenient access to 4-O-glycosylated 1,5-anhydro-d-fructoses via disaccharide-derived 2-hydroxyglycal esters

Efficient six-step protocols are described for the conversion of common disaccharides, such as maltose, cellobiose, or lactose, into the corresponding 4-O-glycosyl-1,5-anhydro-d-fructoses. Overall yields of 40-45% are favorably compared to the alternative eleven-step procedure from their monosaccharide components (～15%).

SELECTIVE DEACYLATION OF ENOL ESTERS WITH HYDROXYLAMINE

An effective procedure for selectively cleaving enol esters in the presence of normal ester functions has been developed, involving hydroxylaminolysis to the oxime of the parent ketone.
