An environment-friendly, simple and efficient one-pot acetylation and benzylidene acetal formation
procedure has been introduced for the synthesis of sugar derivatives using P2O5-Al2O3 as a solid acid
catalyst under solvent-free condition at room temperature, with excellent overall yield. This benzylidene
acetal has been deprotected using the same reagent but in a moist condition.
