The present study was motivated by the possibility of obtaining a compound which could serve as a common intermediate in the synthesis of psoralenes or linear benzodifurane. 6-Hydroxy-5-formylbenzofuran (III) has proven to be just such an intermediate and can be used to prepare unsubstituted psoralene and benzodifuran as well as substituted homologs.
