Various furanosyl and pyranosyl fluorides react rapidly with alkyl, alkenyl, alkynyl, and aryl organoaluminum reagents at or below room temperature to form C-glycosides in 68-93% yields. Effective application of this procedure to a 6-fluoro 1,6-anhydroglucose derivative produced a chain-extended sugar stereospecifically. © 1985.
