The present invention relates to a method of making indeno-fused naphthol materials, that involves, with some embodiments, forming an indanone acid intermediate, which can be represented by the following general Formula V,
With Formula V, m is from 0 to 4, and R
1
for each m, R
g
and R
h
can each be independently selected from, for example, hydrogen and hydrocarbyl. The present invention also relates to a method of making an indeno-fused naphthopyran that involves an indanone acid intermediate synthetic route.
