kinetic resolution of a β-hydroxy amide, a Pd-catalyzed cross-coupling to construct a substituted allylsilane, a highly and stereoselective conjugate addition of lithium dimethylcopper to an α,β-acetylenicester and an elaboration of the C6–C7 trans-olefin geometry by a Julia-Kocienski olefination.

Iriomoteolide-1a and iriomoteolide-1b are very potent cytotoxic agents, isolated from marine dinoflagellates. We carried out the enantioselective syntheses of the proposed structures of these natural products. However, our analysis of the NMR spectra of the synthetic iriomoteolide-1a and the natural products revealed that the structures of iriomoteolide-1a and iriomoteolide-1b were assigned incorrectly.
