Chapter 22, Problem 22.23P

Interpretation Introduction

Interpretation:

The given aldol condensation is to be analyzed. The four possible aldol condensation products in the principle result from the starting materials are to be shown. The reason as to why the observed product is the most reasonable one is to be stated.

Concept introduction:

Aldol condensation is the nucleophilic addition reaction of the carbonyl compounds. An enolate ion generated from one of the carbonyl compound attack the electrophilic carbon of the other carbonyl compound to produce $\beta$-hydroxy aldol or $\beta$-hydroxy ketone. This product further gives dehydration or condensation product by elimination small molecule such as water. Intramolecular aldol condensation means that a molecule itself contains the both functional groups or both centers as aldehyde or ketone groups. One of the groups generates enolate and attacks on other group.
