Abstract

A selective acidic system for partial deacetylation of phenolic d-glucopyranosides per-acetates has been developed that allows synthesis of the corresponding 2'-O-acetyl-D-glucosides. Many disadvantages of generally used methods for preparing such mono-acyl derivatives involving multistep procedures or the use of enzymes are avoided. The ion at m/z 289 in mass spectra of their TMS derivatives indicates a particular and characteristic fragmentation pattern of these 2'-O-acetyl derivatives of d-glucopyranosides. Quantum-chemical calculations applying B3LYP/TZVP level of theory revealed the stability of 2'-O-acetyl glucopyranoside if compare with 3'-, 4'- and 6'- O-acetyl glucopyanosides.

Keywords: Aryl 2′-O-acetyl d-glucopyranoside; Phenolic acyl glycosides; Salireposide.
