A new short synthetic approach to cyclopentaphenanthrenones
The Diels-Alder reactions of 4-acetoxy-2-cyclopenten-1-one and 2-bromo-4- acetoxy-2-cyclopenten-1-one with vinylarenes are discussed. The aromatization of the reaction products opens a new two-step route for the synthesis of cyclopentaphenanthrenones. Structure analysis of reaction products by 1H and 13C-NMR spectroscopy is reported.
