  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.
