Abstract The reaction of acetylated C -( d -glycosyl) heterocycles and d -glycosyl cyanides with either N -bromosuccinimide in hot carbon tetrachloride or bromine under irradiation resulted in bromination at the anomeric carbon atom. The location of the bromine substituent and the conformations of these products were determined by n.m.r. spectroscopy. Absolute configurations of the bromo compounds
