Chapter 20.5, Problem 20.7P

(a)

Interpretation Introduction

Interpretation: The combination of diene and dienophile that undergoes Diels-Alder reaction to give the given adduct, has to be found.

Concept Introduction:

Diels-Alder reaction:

It is the reaction of conjugated dienes with double or triple bonded compounds which are known as “dienophiles”. The reaction is a 4+2 cycloaddition reaction that results in the formation of a six membered cyclic product which is known as “adduct”.

Example:

Organic Chemistry, Chapter 20.5, Problem 20.7P , additional homework tip  1

Organic Chemistry, Chapter 20.5, Problem 20.7P , additional homework tip  2

This mechanism shown that three π-bonds are broken to form two new σ -bonds and a new π-bond.
