Chapter 24: Q.49. (page 962)

Question: What product (including stereochemistry) is formed in each of the following intramolecular reactions?

Short Answer

Expert verified

Answer

Step by step solution

01

Intramolecular aldol reaction

In the presence of the reagents NaOEt and EtOH, the compound undergoes an intramolecular aldol reaction. In this reaction, the α-carbon of one of the carbonyl groups bonds with the carbonyl (C=O)carbon of another carbonyl group.

02

Dieckmannreaction

In this reaction, the ester group and the carbonyl group undergo a reaction to form a cyclic β-ketoesterin the presence of NaOEt and H3O+ reagents.

Question: In theory, the intramolecular aldol reaction of 6-oxoheptanal could yield the three compounds shown. It turns out, though, that 1-acetylcyclopentene is by far the major product. Why are the other two compounds formed in only minor amounts? Draw a stepwise mechanism to show how all three products are formed.
