DOCUMENT TYPE: Patent CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Section cross-reference(s): 1 Pyridopsoralens I (R = H, alkyl, alkoxy) were prepd. Thus, 6-acetoxy-2,3-dihydrobenzofuran with condensed with 1-benzyl-3-ethoxycarbonyl-4-piperidinone to give tetrahydropyridopsoralen II which was debenzylated and aromatized with Pd-C to give I (R = H). I are effective in treating psoriasis. I possess photoaffinity than 8-methoxypsoralen for DNA for which they act as monofunctional ligands. .
