Synthetic approaches to novel 4,8-dimethyl-4’-halomethyl-4’,5’-dihydropsoralens as synthetic precursors to 4,8-dimethyl-4’-(N-pyridiniummethyl)-4’,5’-dihydropsoralens are described. The compounds are potential therapeutic agents for improved psoralen ultraviolet radiation therapy with reduced mutagenicity.
