C-glycosides: A stereoselective synthesis of α-C-galactosamines with a glycosyl dianion

Article abstract of DOI:10.1016/S0040-4039(97)10567-6

α-C-glycosides of the galactosamine can be obtained from the configurationally stable α-glycosyl dianion which can be prepared by reductive lithiation of the chloride. Different electrophiles react selectively at the anomeric center.
