The first totalsynthesis of the proposedstructure of cytotoxic macrolide maltepolide C has been achieved via an E-selective intramolecular Heck cyclization as a key step. Other key features of the synthesis are Z-selective Wittig olefination, Sharpless asymmetric dihydroxylation followed by Williamson-type cyclo-etherification, Brown asymmetric allylation, and Noyori reduction of an alkynone.
