Chapter 22, Problem 43P

Interpretation Introduction

Interpretation:

The explanation for physical property (here, boiling point) of a compound based on its structural formula is to suggested.

Concept introduction:

$\text{Methyl 2,3}-\text{anhydro}-\text{D}-\text{ribofuranoside}$ exists in both $\alpha -\text{and }\beta -$ anomeric forms. The two forms show ring conformations with methoxy and hydroxymethyl substituents involved in intra-molecular hydrogen bonding.

The $\text{NMR}$(nuclear magnetic resonance)-based studies on ribofuranoside conformations revealed the above information. The NMR is an analytical technique in chemistry to identify the structure of a compound. It is an important tool in structure elucidation of organic compounds.
