An efficient synthesis of (+)-8a,9-secoartemisinin 2, ring-D cleaved, tricyclic analog of (+)-artemisinin 1, has been accomplished. Dioxetane7, produced upon ozonolysis of vinyl-silane 5 in methanol, was intercepted with acid to provide the stable bicyclic peroxy-aldehyde9, which was readily converted to the title compound(s).
