Chapter 20, Problem 53P

Interpretation Introduction

Interpretation:

The $\text{D}-\text{aldopentose}$ given in the sequence of reactions has to be identified.

Concept Introduction:

The Wohl degradation is the opposite of Kiliani Fischer synthesis which decreases the aldose chain by one carbon atom that is hexoses having ix carbons are converted to pentoses having five carbon and pentoses having five carbons are converted to tetroses having four carbons.
