2-Deoxyglycosides were synthesized in high α-selectivity by the direct addition of alcohols to D-glucal and D-galactal catalyzed by TMSI and PPh(3). The acid labile isopropylidene group is tolerated under this condition.

Novel one-pot three- and four-component transformations of D-glucal to furan-based hydroxy triazole glycoconjugates have been achieved by sequential addition of reagents in the presence of Cu(OTf)(2)-Cu powder as catalysts. In general the carbohydrate-derived products were formed with high diastereomeric purity.
Cellobiose phosphorylase from Cellulomonas uda (CuCPase) is shown to utilize D-glucal as slow alternative donor substrate for stereospecific glycosyl transfer to inorganic phosphate, giving 2-deoxy-α-D-glucose 1-phosphate as the product. When performed in D(2)O, enzymatic phosphorolysis of D-glucal proceeds with incorporation
