Abstract
UV irradiation of 4''-hydroxymethyl-4,5'',8-trimethyl psoralen (HMT) in aqueous solution yields three major photoproducts. We have isolated and characterized (1) a cyclobutane-bridged dimer in which a cis-syn linkage occurs between the furan end of one HMT moiety and the pyrone end of the other; (2) a cyclobutane-bridged dimer wherein both HMT moieties are linked at their pyrone ends with probable cis-syn configuration; and (3) an isomer of HMT for which we have proposed a structure in which the furan and pyrone ring oxygens assume a para orientation via photoisomerization.This publication has 25 references indexed in Scilit:
