Abstract: The course of partial hydrolysis of O-acyl derivatives of methyl α- and β-D-xylopyranosides as well as of 4-methylumbelliferyl β-D-xylopyranoside has been followed in dependence on the reaction medium (methanolysis, hydrazinolysis), anomeric arrangement on C-1, and type of the acyl groups (acetyl, benzoyl). The obtained results have shown that the course of hydrolysis is influenced mainly by anomeric arrangement on C-1 and by the reaction medium. Eighteen mono- and di-O-acyl derivatives of methyl α- and β-D-xylopyranosides and nine mono- and di-O-acyl derivatives of 4-methylumbelliferyl β-D-xylopyranoside have been prepared.
