Chapter 23.11, Problem 19P

Interpretation Introduction

a)

Interpretation:

The product that will be produced when the enamine obtained by reacting cyclopentanone and pyrrolidone with α, β- unsaturated acceptor, ethyl acrylate, is to be identified.

Concept introduction:

The enamine obtained by reacting a ketone with cyclic amine reacts with α, β- unsaturated acceptor to yield a substituted enamine as the intermediate which upon hydrolysis gives the product.

To identify:

The product that will be produced when the enamine obtained by reacting cyclopentanone and pyrrolidone with α, β- unsaturated, ethyl acrylate, is hydrolyzed.

Interpretation Introduction

b)

Interpretation:

The product that will be produced when the enamine obtained by reacting cyclopentanone and pyrrolidone with α, β- unsaturated acceptor, acrolein is to be identified.

Concept introduction:

The enamine obtained by reacting a ketone with cyclic amine reacts with α, β- unsaturated acceptor, acrolein, to yield a substituted enamine as the intermediate which upon hydrolysis gives the products.

To identify:

The product that will be produced by the hydrolysis of the enamine obtained by reacting cyclopentanone and pyrrolidone with α, β- unsaturated acceptor, acroline.

Interpretation Introduction

c)

Interpretation:

The product that will be produced when the enamine obtained by reacting cyclopentanone and pyrrolidone with α, β- unsaturated acceptor, pent-3-ene-2-one, is to be identified.

Concept introduction:

The enamine obtained by reacting a ketone with cyclic amine reacts with an α, β- unsaturated acceptor to yield a substituted enamine as the intermediate which upon hydrolysis gives the products.

To identify:

The product that will be produced by the hydrolysis of the enamine obtained by reacting cyclopentanone and pyrrolidone with α, β- unsaturated acceptor, pent-3-ene-2-one.
