SYNTHESIS OF (+/-)-5-HYDROXYMARMESIN: BIOGENETIC PRECURSOR OF THE SKIN PHOTOSENSITIZING AGENT BERGAPTEN

The synthesis of (+/-)-5-hydroxymarmesin is described.The 5,7-diacetoxycoumarin was selectively C(8) isoprenylated, the isoprenylated intermediate underwent oxidative cyclization to (+/-)-5-hydroxycolumbianetin, which was transformed into (+/-)-5-hydroxymarmesin by alkali treatment.Preliminary experiments showed that this compound has a biogenetic role in the biogenesis of the skin photosensitizing agent bergapten (5-MOP).
