1,5-Anhydro-D-galactitol

CAS: 3971-48-0

1,5-Anhydro-D-galactitol is a synthetic compound that is an intermediate in the synthesis of melibiose. It is produced by the reaction of acetyl groups with 1,5-anhydro-D-xylose, which is in turn obtained from xylose by hydrolysis or hydrogenolysis. The reaction proceeds efficiently and selectively because the hydroxyl group on the carbon atom adjacent to the carbonyl group on 1,5-anhydro-D-xylose reacts with acetyl chloride to form an ester. This process has been shown to produce two different isomers: erythritol and threitol. The erythritol can be converted into D-fructose and D-ribulose by a process called reductive amination. NMR spectra have been used to confirm that this synthetic process produces only one type of product with a high yield.BR>BR>
