Structure and reactivity of glycosides: IV. Koenigs-Knorr synthesis of aryl β-D-glucopyranosides using phase-transfer catalysts

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 phase-transfer catalysts in glycosylation of phenols. 2001 MAIK "Nauka/Interperiodica".
