Substituted 2,3,4,5-tetrahydrocyclohepta[c]furo[3,2-g]chromen-6-ones, modified psoralen analogs containing a cycloheptane ring annellated to the 5,6-positions of a furo[3,2-g]chromen-7-one, were synthesized from 3-hydroxy-8,9,10,11-tetrahydrocyclohepta[c]chromen-6-ones.
以2,3,4,5-四氢环庚[c]呋喃[3,2-g]色烯-6-酮为代表的取代物,这类修饰的补骨脂素类似物在呋喃[3,2-g]色烯-7-酮的5,6位置上稠合了一个环庚烷环,是由3-羟基-8,9,10,11-四氢环庚[c]色烯-6-酮合成得到。
