Studies Towards a Total Synthesis of Amphidinolide B. Stereocontrolled Synthesis of the C14-C26 Polyol Fragment

A practical synthesis of the C14-C26 polyol unit 2 in amphidinolides B1 and B2, 1, is described which involves elaboration of the chiral unsaturated aldehyde 4 and the chiral ketone 5, followed by crossed-aldolisation of 4 and 5 in the presence of LiHMDS at -78 deg C, as key steps.
