The Diels-Alder reaction of 1-vinylcyclohexene with aconitic anhydride gives the adduct 5b which has the reversed stereochemistry of that predicted by Alder's endo rule. On the other hand, reactions with chloromethylmaleic anhydride and citraconic anhydride afford endo-adducts 23 and 24, respectively. Adduct 23 has the appropriate stereochemistry and functionality for the syntheses of clerodane and
