Chapter 11, Problem 44P

Interpretation Introduction

Interpretation:

The Diels Alder adducts are to be identified.

Concept introduction:

>

The conjugate addition of alkene to diene is the Diels–-Alder reaction occurring through formation of six-membered cyclic transition state.

>

Dienophile is the alkene that adds to diene.Diene is an electron-rich system that attacksan electron deficient dienophile.

>

For retro Diels–-Alder, diene, and dienophile can be identified from the target molecule.

>

If the target molecule has a cyclohexane ring, identify the double bond that can disconnect in a way to form $\text{1,3}$ diene and dienophile having electron withdrawing group attached.
