Monoacetylation of carbohydrate diols via transesterification with ethyl acetate
Liu, Xuyu,Becker, Bernd,Cooper, Matthew A.
, p. 679 - 683 (2014/05/06)
Monoacetylation of secondary diols in protected monosaccharides was achieved with ethyl acetate as acyl donor and sodium tert-butoxide as a base. The regioseletivity of the reaction varied depending on the substrate. This new method provides a simple, fast, and efficient method to access selectively acetylated carbohydrates that is compatible with acid-sensitive protecting groups. CSIRO 2014.
Mild and efficient method for the cleavage of benzylidene acetals using HClO4-SiO2 and direct conversion of acetals to acetates

HClO4-SiO2 has been used successfully for the deprotection of benzylidene acetals and the direct conversion of benzylidene acetals to the corresponding di-O-acetates. The reactions are very fast and yields are excellent.
An easy approach for the acetylation of saccharidic alcohols. Applicability for regioselective protections

Cheap 4 ? molecular sieves can promote acetylation of carbohydrate hydroxyl functions with Ac2O in absence of any co-reagent. The procedure is compatible with the presence of a variety of acid labile protecting groups and can be exploited for regioselective protections.
