Glycosylation of benzothiazolone-2, 5-methylbenzoxazolone-2, and benzothiazolone-2 with the full acetate of a-D-glucosaminyl chloride in the phase transfer systems investigated (solid-organic solvent and aqueous alkali-organic solvent) regioselectively leads to the corresponding N-beta-D-glucosaminides, which is proved by H-1 NMR spectroscopy and X-ray analysis.
