Significance

Lactimidomycin is an antiproliferative macrolide and cell migration inhibitor with a strained twelve-membered 1,3-diene ring. This first synthesis consists of a counterintuitive temporary increase of ring strain using an alkyne ring-closing metathesis to give the Z-enyne H, before reducing this regioselectively and appending the side chain stereoselectively using a Mukaiyama ­aldol reaction.
