    • 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).
    • 本发明涉及使稠合环化合物如茚并稠合的萘酚和茚并稠合的萘并吡喃化合物,如茚并稠合的萘并吡喃,各自使用由下式II表示的不饱和化合物的方法。 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 )。
