A new shorter synthesis of 2-vinyl-3,4-dihydro-naphthalene has been described.The Diels-Alder reactions of this diene with 4-acetoxy-2-cyclopenten-1-one, 3-bromoindan-1-one and inden-1-one under high pressure conditions are reported.A two step synthesis of cyclopenta- and indenophenanthrenones is discussed.Structure analysis by 1H and 13C NMR spectroscopy is presented.
