Rapid glycosylations under extremely mild acidic conditions. Use of ammonium salts to activate glycosyl phosphites via P-protonation

Trifluoromethanesulfonic acid salts of tertiary amines were employed as extremely mild acidic activators for rapid glycosylations. Glycosyl phosphite triesters bearing an acid-labile 4,4′-dimethoxytrityl (DMTr) group for transient protection worked as gly

Direct synthesis of pseudo-disaccharides by rearrangement of unsaturated disaccharides

The series of unsaturated disaccharides 10-14 undergo stereoselective reductive rearrangement with TIBAL (triisobutylaluminium) to afford (1→4) and (1→6) ether-linked pseudo-disaccharides 2-9.
