Several methods for the synthesis of 4-hydroxycoumarin have been described in the literature, most of which use simple phenol and 1-(2-hydroxyphenyl)ethanone or 2'-hydroxyacetophenone as starting compounds. Other synthesis pathways exist, but they are based on intermediate synthesis compounds. About ...
