The total syntheses of marine natural products belonging to the kainoid family, isodomoic acids G and H are described. The strategic connection involves a sequential silylcarbocyclization/silicon-based cross-coupling process. These total syntheses were achieved efficiently via a twelve and a thirteen step, longest-linear sequence, respectively. The key transformations include a diastereoselective rhodium-catalyzed carbonylative silylcarbocyclization reaction of a (L)-vinylglycine-derived 1,6-enyne, a desilylative iodination reaction, as well as an alkenyl-alkenyl silicon-based cross-coupling reaction. The mechanistic insight garnered during the investigation of the iododesilylation reaction enabled stereocontrolled introduction of the iodine with either inversion or retention of double bond configuration. The invertive desilylative iodination leads to the total synthesis of isodomoic acid H, while its congener, isodomoic acid G, was obtained via a retentive iododesilylation.
