    • The present invention relates to methods of making fused ring compounds, such as indeno-fused naphthols, and fused ring indenopyran compounds, such as indeno-fused naphthopyrans, that each employ an unsaturated compound represented by the following Formula II. Referring to the unsaturated compound of Formula II: Ring-A can be selected from optionally substituted aryl (e.g., phenyl); m can be, for example, from 0 to 4; R1 for each m can be selected from optionally substituted hydrocarbyl (e.g., C1-C6 alkyl) optionally interrupted with at least one linking group (e.g., —O—); and R3 and R16 can each be independently selected from, for example, hydrogen or optionally substituted hydrocarbyl, such as C1-C8 alkyl. When Ring-A is a phenyl group, the unsaturated compound represented by Formula II can be referred to as an unsaturated indanone acid/ester compound, or an indenone acid/ester compound (depending on whether R16 is hydrogen, or an optionally substituted hydrocarbyl group).
    • 关于式II的不饱和化合物:环-A可以选自任选取代的芳基(例如苯基); m可以是例如0至4; 每个m的R 1可以选自任选被至少一个连接基团(例如-O-)中断的任选取代的烃基(例如C 1 -C 6烷基); 并且R 3和R 16各自独立地选自例如氢或任选取代的烃基,例如C 1 -C 8烷基。 当环A是苯基时,由式II表示的不饱和化合物可以称为不饱和茚酮酸/酯化合物或茚酮酸/酯化合物(取决于R 16是氢还是任选取代的烃基 )。
