Chapter 14.SE, Problem 57AP

Interpretation Introduction

Interpretation:

The structure of the product with molecular formula C₁₇H₁₆O₆ formed when the triene shown reacts with 2 equivalents of maleic anhydride is to be given.

Concept introduction:

The reaction given involves two Diels-Alder reactions. In Diels-Alder reaction, a dienophile reacts with a diene to yield a cyclic adduct. The reaction takes place through 1,4 addition of the dienophile into the diene through a cyclic transition state. These reactions occur rapidly with dienophiles having electron withdrawing substituent groups in conjugation with the double bond and if the diene adapts a s-cis conformation during the reaction.

To give:

The structure of the product with molecular formula C₁₇H₁₆O₆ formed when the triene shown reacts with 2 equivalents of maleic anhydride.
