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

O-Alkylierung am anomeren Zentrum, 4. 1-O-Alkylierung von D-Mannofuranose und D-Mannopyranose

From 1-O-metallated 2,3;5,6-di-O-isopropylidene-D-mannose (1) and strong alkylating agents (triflates) β-D-mannofuranosides were obtained, addition of crown ether resulted in α-D-mannofuranoside formation.From the 6-O-unprotected D-mannose 7 a similar ste
