Abstract

Reaction of 5,6-benzocyclohexan-1-one with formaldehyde in the presence of bases gives the Diels—Alder dimer of the intermediate 2-methylene-5,6-benzocyclohexan-1-one and the expected methylenebis-5,6-benzocyclohexan-1-one. The optimal conditions for the formation of the dimer and its conversion into the hydroxy-1,6-diketone are found. The reactions of these products with H2S and acids are studied. The structures of the newly prepared compounds are confirmed by 13C NMR.
