Аннотация: 2(5)-Substituted 4-hydroxy-3,4-diphenylcyclopent-2-en-1-ones easily react with 2.5 molar excess of maleic anhydride to give 1(4)-substituted 7,8-diphenylbicyclo[2.2.2]oct-7-ene-2,3,5,6-tetracarboxylic acid dianhydrides containing alkyl groups at bridgehead of the bicycle. The stereochemistry of the obtained bicyclic bis-anhydrides was determined to be syn-syn.
