The synthesis and the photobiological activity of newtetrahydrobenzo- and benzofurobenzopyrone derivatives carrying at position 4 of benzopyrone ring of furobenzopyrone moiety a phenyl, or a methyl group with a linear structure or with various angular arrangements, are reported. The new compounds are characterized by having an additional cyclohexene or phenyl ring condensed at the 2, 3 double bond
