A convergent asymmetric synthesis of the polyether antibiotic ferensimycin B has been completed. Chiral enolate bond constructions were employed to establish seven of the 16 stereocenters of the subunits 35 and 52, which comprise the C1-C-9 and C-10-C23 portions of ferensimycin B. The stereogenic ce...
