| The Diels-Alder reaction is a standard reaction taught in undergraduate organic chemistry courses and laboratories. One of the best examples involves the reaction of alpha-phellandrene with maleic anhydride in refluxing ether to produce a wonderful white crystalline product. However, standard analyses of this reaction product rarely proceed past the level of melting point determination. An excellent opportunity exists here for students to explore in depth the three-dimensional structure of this Diels-Alder adduct. Herein, we report the utilization of several spectroscopic strategies that students can employ to elucidate the structure of the adduct. In particular, several NMR techniques can be used to assign proton and carbon signals and X-ray analysis can be utilized to assign the stereochemistry to the single chiral center in the product molecule. |
