Longimicin C, a naturally occurring annonaceous acetogenin possessing a C2-symmetrical bis-THF moiety and a short hydrocarbon chain between its THF-containing region and a terminal γ-lactone, was synthesized for the first time. The totalsynthesis was successfully achieved by an iterative acetylene–epoxide coupling strategy. d-Mannitol was used to establish the bis-THF-containing segment, in which

to the isolation of four novel bioactive annonaceous acetogenins: longimicins A-D (1-4). Compounds 1-4 represent the asimicin type of acetogenins; however, the locations of the adjacent bis-tetrahydrofuran (THF) ring moieties are shifted along the aliphatic chains compared to the known compounds of this type. They are the first examples among this type of acetogenins with the placements of the ring
