(544v) Catalytic Glycosylation of Glucose with Fatty Alcohol over Sulfonated Mesoporous Carbons

Herein we prepared various sulfonated mesoporous carbons through the nanocasting method using a mesoporous SBA-15 as a mold. After complete characterization, the catalytic performances of the as-obtained sulfonated mesoporous carbons were assessed in the glycosylation of carbohydrates with alkyl alcohols. Under optimized conditions, the targeted alkyl glycosides were obtained in 85% yield, together with a turn over frequency and a space time yield even higher than those of the best heterogeneous catalysts reported so far in such reaction. Furthermore, we showed that sulfonated mesoporous carbons have the advantage of being more stable than common solid acid catalysts, allowing their recycling.
