glucosamine donor 2 reacts with electron-rich phenol ethers 3a–c to afford aryl C-glycosides 4a–c. The N-tetrachlorophthaloyl group could be readily removed by sodium borohydride treatment and then phthalide formation or by treatment with ethylenediamine, respectively. The resulting product was subjected to reaction with acetic anhydride in pyridine to afford N,O-acetylated compounds 5a–c. After treatment
