Solution

The correct option is D 1: Diels-Alder of butadiene and the substrate;
2; Catalytic hydrogenation

Observe the stereochemical data on either side of the equation – both Cl and COOH groups remain trans;
This points to a nifty implementation of the Diels-Alder reaction:


The product from above on catalytic hydrogenation completes the synthesis.

the scientist duo Otto Diels and Kurt Alder a Nobel prize in Chemistry in 1950.
