synthesis of its C-4 epimer. Key reactions of the synthetic pathway include a Jacobsen hydrolytic kinetic resolution of an epoxide followed by its regioselective opening through a Yamaguchi–Hirao alkynylation, and ring-closingmetathesis reaction to furnish the unique 14-membered ring macrolactone. In addition, the influence of protecting groups on the efficiency of the ring-closingmetathesis (RCM) macrocyclization

The design, syntheses, and biological evaluation of 22 totally synthetic analogues of the potent microtubule-stabilizing agent (divided by)-discodermolide (1) have been achieved. Structure-activity relationships of the C(19) carbamate were defined. exploiting two synthetically simplified scaffolds. as well as the parent (+)-discodermolide framework.

The design, syntheses, and biological evaluation of nine totally synthetic analogues of the microtubule-stabilizing agent (divided by)-14-normethyldiscodermolide (2) are reported. Simplification at the C(21)-C(24) terminal diene and at the C(1)-C(5) lactone moieties reveals significant structure-activity relationships.
