    to the characteristic flavors and aromas that are found in the essential oils of many plants. Some of these dienes are conjugated and have the ability to make Diels-Alder adducts with maleic anhydride. The Diels-Alder reaction is the conjugate addition of an alkene to a diene. In order for a Diels...
