Chapter 21, Problem 53PP

(a)

Interpretation Introduction

Interpretation:

To draw the enolate formed when a set of given compounds is treated with LDA.

Concept introduction:

When an base deprotonates a carbonyl compound in its α position and enolate is formed.  If LDA is used as base for deprotonation the hydrogen is completely removed as it is a strong base.

Please bear in mind that LDA is a strong, sterically hindered base, so it deprotonates the less substituted α carbon.
