Reaction Steps
1,4-Anhydro-D-glucitol may be prepared using the procedure disclosed in Acta Chem. Scand., B35, 441-449 (1981), whereby D-sorbitol is heated with an aqueous mineral acid such as sulfuric acid. The L-enantiomer, 1,4-anhydro-L-glucitol, may be prepared from L-glucitol by an analogous procedure. L-glucitol may be prepared by sodium borohydride reduction of L-glucose. The D and L enantiomers may simply be combined to form a 1,4-anhydro-DL-glucitol mixture.
