Chapter 24, Problem 43P

Interpretation Introduction

Interpretation:

From the given starting material the complete synthesis of the given product is to be written.

Concept introduction:

The hydroxyl groups of carbohydrates can be alkylated on reaction with benzyl chlorides.

The triphenylmethyl chloride reacts selectively with primary alcohols $\text{C-6}$ in hexose.

The ether formed at $\text{C-6}$ in hexose by the reaction of triphenylmethyl chloride can be selectively removed by mild acid hydrolysis without disturbing methyl glycoside.
