Lactimidomycin (1) was described in the literature as an exquisitely potent cell migration inhibitor. Encouraged by this claim, we developed a concise and scalable synthesis of this bipartite glutarimide‐macrolide antibiotic, which relies on the power of ring‐closing alkyne metathesis (RCAM) for the formation of the unusually strained 12‐membered head group. Subsequent deliberate digression from the

macrocyclizations as a complete removal of these unsaturation units resulted in exclusive formation of the dimer rather than monocyclic enoate. The synthetic route features a late‐stage installation of the glutarimide functionality via an asymmetric catalytic Mukaiyama aldol reaction, which allows for a quick generation of lactimidomycin homolog 55 containing two additional carbons in the glutarimide side

An efficient total synthesis of the antiproliferative macrolide and cell migration inhibitor lactimidomycin (3) is reported, which relies on the performance of ring closing alkyne metathesis (RCAM). The strained 12-membered 1,3-enyne 21 as the key intermediate was forged with the aid of [(Ph(3)SiO)(3)Mo≡CPh]·OEt(2) (27) as the most effective member of a new generation of powerful alkyne metathesis

An enantioselective synthesis of potent eukaryotic translation elongation inhibitor lactimidomycin has been accomplished in 21 linear steps. This synthesis features a Zn(II)-mediated Horner-Wadsworth-Emmons reaction that could be executed on a large scale to provide the highly strained 12-membered lactimidomycin macrolactone.
