Thermal conversion of the epidioxydihydrofurans 1 leads, via dioxetanes 3, to the stereoisomeric dimers 4 which have a structural relationship with antitumour cyclic peroxides and represent convenient starting materials for several multifunctional compounds; their mild acid hydrolysis provides a convenient entry to the synthesis of the furanone derivatives 7 and 8 which are structurally related to biologically active products.
