The C19–C28 model fragment 2 of concanamycin A (1) was prepared by a Mukaiyama aldol reaction between silyl enol ether 11 and aldehyde 4 to give 7, followed by glycosylation with activated sugar 14 or 15.

cross-coupling reaction between the C1–C13 vinyl iodide and C14–C22 vinyl stannane fragments to assemble the (12E,14E)-diene, a modified Yamaguchi macrolactonisation delivered the requisite 18-membered macrocyclic core. This advanced intermediate was also obtained by an alternative sequence using an esterification step to connect the C1–C13 and C14–C22 fragments followed by a Pd-catalysed intramolecular
