Glycosyl imidates, 76: Synthesis of aryl C-glycosides of glucosamine
Castro-Palomino, Julio C.,Schmidt, Richard R.
, p. 1623 - 1626 (2007/10/03)
The N-tetrachlorophthalimido-protected 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 formatio
