Modified pyranocoumarins containing a condensed cyclopentane fragment were synthesized by adjoining a 2,2-dimethyltetrahydropyran ring to a 2,3-dihydrocyclopenta[c]chromen-4-one system and annelation of a pyrone ring to a 2,2-dimethylchromane.
含有稠合环戊烷片段的改性吡喃香豆素通过将2,2-二甲基四氢吡喃环连接到2,3-二氢环戊并[c]色烯-4-酮体系,并将吡喃环并联到2,2-二甲基色烷上合成得到。
