The first total synthesis of pectinolides D and E and total synthesis of pectinolides A and C was achieved from a hitherto unknown common key building block prepared from readily available D-mannitol. Key reactions involved in the synthesis are Red-Al reduction of an epoxy alcohol, enantioselective Noyori reduction of ynones, aldehyde-alkyne coupling, and Still-Genari cis-olefination.
