The first asymmetrictotalsynthesis of the unnatural enantiomer of cytotoxic awajanomycin (1) is reported. The synthetic approach features first a convergent strategy using the cross-olefin metathesis reaction to link the lipid side chain 2 and the piperidinone core structure 3. The second feature of the synthesis resides on the construction of segment 3 from the building block 5 via a three-component
