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).
本发明涉及制造熔融环化合物(如茚并熔合萘酚)和熔融环茚并吡喃化合物(如茚并熔合萘并吡喃)的方法,其中每种化合物都采用下式 II 所代表的不饱和化合物。
关于式 II 的不饱和化合物:环-A 可以选自任选取代的芳基(如苯基);m 可以是例如 0 至 4;每个 m 的 R1 可以选自任选取代的烃基(如 C1-C6 烷基),任选与至少一个连接基团(如 -O-)间断;R3 和 R16 可以各自独立地选自例如氢或任选取代的烃基,如 C1-C8 烷基。当环-A 为苯基时,式 II 所代表的不饱和化合物可称为不饱和茚酮酸/酯化合物或茚酮酸/酯化合物(取决于 R16 是氢还是任选取代的烃基)。
