The structure of the product with molecular formula C 17 H 16 O 6 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 C 17 H 16 O 6 formed when the triene shown reacts with 2 equivalents of maleic anhydride.

If possible, replace an H atom on the a carbon of the molecule in the drawing area with a methyl group substituent, and replace an H atom on the ẞ carbon with a hydroxyl group substituent. If one of the substituents can't be added for any reason, just don't add it. If neither substituent can be added, check the box under the drawing area. en HO OH
