Abstract :The reactions of some 1,3-dicarbonyl compounds with cycloheptatriene derivatives in the presence of Mninsert ignore into journalissuearticles values(OAc);3 were examined. Cycloheptatriene forms mainly [2+3] and [6+3] dihydrofuran addition products derived from cycloheptatriene. However, the reaction of acetylacetone with cycloheptatriene substituted with an electron withdrawing group exclusively gave products derived from the norcaradiene structure. The formation mechanism of the products as well as the role of the substituent attached to cycloheptatriene is discussed.
