A. Chenede et al., SYNTHESIS OF C-DISACCHARIDES BY A SAMARIUM DIIODIDE INDUCED INTRAMOLECULAR COUPLING REACTION OF TETHERED SUGARS, Synlett, (6), 1994, pp. 420-422
C-disaccharides.7 and 14 were expeditiously synthesized by SmI2 promot
ed radical coupling of glucosyl phenyl sulfones 4 and 13 onto the temp
orarily tethered exomethylene sugar 5.
