Show how Diels–Alder reactions might be used to synthesize

Step 1 of 10

Diels-Alder reaction: The cyclo addition reaction of a diene with a dienophile yields a cyclo hexene. 1,3 butadiene undergoes cyclo addition reaction with ethylene (diene) to form cyclohexene. This reaction takes place through a six-membered cyclic transition state.

The reaction is as follows:
