Modified coumarins. 4. Synthesis and biological properties of cyclopentane-annelated furocoumarins

Psoralen and allopsoralen analogs that contain an annelated cyclopentane were synthesized from 7-hydroxy- and 9-hydroxy-1,2,3,4-tetrahydrocyclopenta[c]chromen-4-ones. 9-Phenyl-1,2,3,4-tetrahydrocyclopenta[c]furo[3,2-g]chromen-4-one exhibited low toxicity,
