Abstract

The photocycloaddition of 8-methoxypsoralen to cyclothexene and to heptene-1 was found to give 3,4-dihydrobicyclo (4,2,0) octano (7",8":3,4) 8-methoxypsoralen (4) and a mixture of 3, 4-dihydro-(1-n-pentyl) cyclobutano-(2", 3":3,4) 8-methoxypsoralen (5) and the isomer 6 respectively. Stern-Volmer plot and quenching studies indicate that the reaction proceeds via psoralen triplet excited state.
