dihydroalkanoquinones which, depending on their structures, react with in situ generated hydroperoxide anion to give quinoneepoxides and/or hydroperoxides. The calcium hydroxide-induced rearrangement of quinoneepoxides yielded furan-containing angular quinones. The cytotoxic activities of quinoneepoxides and their isomerization products were evaluated in vitro against normal human lung fibroblasts (MRC-5) and
