An efficient and regioselective approach for the construction of synthetically important γ-lactone glycosides is reported from unprotected aldoses through a new debenzylative lactonization (DBL) reaction. The scope and limitations of this DBL reaction are described starting from a series of commercially available hexoses (l-fucose, d-galactose, d-glucose) and pentoses (d-arabinose, d-ribose, d-lyxose, d-xylose) to afford the corresponding γ-lactones in good yields and without concomitant δ-lactone formation.

A highly regioselective synthesis of valuable gem-difluorinated C-furanosides from unprotected aldoses via a debenzylative cycloetherification (DBCE) reaction induced by diethylaminosulfur trifluoride is descibed. The scope and limitations of this DBCE reaction are described using a series of commercially available pentoses and hexoses to afford, without selective protection/deprotection sequences, the corresponding gem-difluorinated C-furanosides in moderate to good yields.
