2,3,5-Tri-O-benzyl-D-ribono-1,4-lactone is a synthetic building block which can undergo reaction with nucleophilic carbon species to afford C-ribosides (via the corresponding hemiacetal). Treatment of 2,3,5-Tri-O-benzyl-D-ribono-1,4-lactone with stronger reducing agents, such as sodium borohydride, affords ring opened products with a stereo-defined poly-oxygenated carbon chain backbone.
