Totalsynthesis of alternaria toxins starting from previously synthesized altenuene (3) and isoaltenuene (4) is described. Dihydroaltenuene B (9) was prepared by hydrogenation of 3, and the non-natural epimer 3-epi-dihydroaltenuene A was obtained analogously from 4. Inspection of the spectroscopic data for 9 revealed that the originally proposed structure was in error. A revised structure (11), unambiguously
