Concept introduction:
Ruff degradation is a method which is used to shorten sugar chain. It is a two step process which starts with a bromine-water oxidation of the aldose to its aldonic acid. Then in the second step treatment of aldonic acid with hydrogen peroxide and ferric sulfate oxidizes the carbonyl group to

- Compound A is a D-aldopentose that can be oxidized to an optically inactive aldaric acid B. On Kiliani-Fischer chain extension, A is converted into C and D; C can be oxidized to an optically active aldaric acid E, but D is oxidized to an optically inactive aldaric acid F. What is the structure of compound F? • Use the wedge/hash bond tools to indicate stereochemistry where it exists. You do not have to explicitly draw H atoms. If a group is achiral, do not use wedged or hashed bonds on it. • Show stereochemistry in a meso compound. • Do not include lone pairs in your answer.
