(canceled) This application claims the benefit of U.S. Provisional Patent Application No. 61/459,613, filed on Dec. 16, 2010 which is incorporated herein by reference in its entirety.The present invention relates to methods of making fused ring compounds and fused ring indenopyran compounds that each involve the use of certain unsaturated compounds.Indeno-fused ring compounds, such as A and B ring fused inden-6-ol compounds, have many uses, such as intermediates in the synthesis of photochromic compounds and materials, such as indeno-fused ring pyran compounds, including A and B ring fused indenopyran compounds. Photochromic materials, such as indeno-fused naphthopyrans, in response to certain wavelengths of electromagnetic radiation (or “actinic radiation”), typically undergo a transformation from one form or state to another form, with each form having a characteristic or distinguishable absorption spectrum associated therewith. Typically, upon exposure to actinic radiation, many photochromic materials are transformed from a closed-form, which corresponds to an unactivated (or bleached, e.g., substantially colorless) state of the photochromic material, to an ...
