During the preparation of simple mannopyranosides using the Koenigs-Knorr type reaction, we observed that a significant amount of disaccharide glycoside was produced when the alcohol was used in amounts less than equivalent of 2,3,4,6-tetra-O-acetyl-c~-D-mannopyranosyl bromide ("acetobromomannose").
