In addition, a computational study on the deacylation of ¦Â-D-glucose pentaacetate has been carried out with density functional theory (B3LYP/6-31G*). The anomeric effect during deacetylation and dealkylation has been clearly demonstrated in both experimental and computational results. %K deacetylation %K dealkylation %K anomeric effect %K deacylation %K density functional theory %U http://www.mdpi.com/1420-3049/15/1/374
