Penta-O-acetylglucose

Glucose is first esterified to penta-O-acetylglucose using acetic anhydride. Note that the hemiacetal hydroxyl is also esterified, and thus any equilibration with an aldehyde form is now not possible (see Section 7.2). When this penta-acetate is treated with HBr, the anomeric acetate is preferentially lost under the acidic conditions, due to the stabilization conferred by the heterocyclic oxygen. Note that this is the same type of intermediate we implicated... [Pg.479]
