Abstract 1,2- O -Isopropylidene-5- O -toluene- p -sulphonyl-β- d -arabinofuranose has been converted into 5-thio- d -arabinose via 3- O -acetyl-5- S -acetyl-1,2- O -isopropylidene-5-thio-β- d -arabinofuranose. 5-Thio- d -lyxose was similarly obtained from methyl 2,3- O -isopropylidene-5- O -methanesulphonyl(or toluene- p -sulphonyl)-α- d -lyxofuranoside via methyl 5- S -acetyl(or benzoyl)-1,2- O -
