Abstract
A series of acetylated aryl β-D-glucopyranosides were prepared in 12-63% yields from tetra-O- acetyl-α-D-glycopyranosyl bromide and phenols containing acyl, formyl, and hydroxy substituents, and also from sterically hindered phenols in the two-phase system chloroform-aqueous alkali in the presence of triethylbenzylammonium chloride. Hydroxyethylated sucrose and dibenzo-18-crown-6 do not behave as phasetransfer catalysts in glycosylation of phenols.
