Abstract

The regioselectivity in the Diels–Alder reaction of 9-substituted anthracenes having electron-releasing substituents with citraconic anhydride has been investigated. The ortho regioisomer is preferred in all the cases with good yield. The reaction proceeded best under conventional heating conditions in toluene.
