Glycosylation of various phenols with alpha -D-glucosaminyl chloride peracetate in a solid phase-liquid system catalyzed by crown compounds was studied. The highest yields of aryl beta -glycosides were observed at room temperature in acetonitrile using anhydrous potassium carbonate as a base. The optimum phenol-glycosyl donor-base-crown ether ratio was 1 : 1 : 1 : 0.2.
