4-Hydroxycoumarin forms the nucleus of many natural products and drugs. It is a key intermediate for the widely used oral anticoagulants and rodenticides. There is interest in fused pyranochromenes because chromene derivatives can be used as immunomodulators and for the treatment of different diseases of connective tissues, diabetes, etc. We present here the synthesis and crystal structure of the title compound, (I). The molecule is being assessed for biological activity.
