Abstract A new synthetic route to aminomethylpsoralens, substituted on the furan-ring, has been developed by electrophilic substitution of N-hydroxymethylphthalimide and subsequent hydrazinolysis. Hydroxy and methoxy activating functions on the psoralens lead to multi-site substitution and the products of these phthalimido-methylations resist simple cleavage with hydrazine. The two-step introduction of a single CH 2 NH 2 group is ...
