Stereoselective synthesis of the C1-C29 part (I) of amphidinol 3 (AM3) was achieved. The C1-C20 part was assembled from three building blocks via regioselective cross metathesis to form the C4-C5 double bond and addition of an alkenyllithium and a lithium acetylide to two Weinreb amides followed by asym. reduction to form the C9-C10 and C14-C15 bonds, resp. The C21-C29 part was synthesized via successive cross metathesis and oxa-Michael addition sequence to construct the 1,3-diol system at C25 and C27 and Brown asym. crotylation to introduce the stereogenic centers at C23 and C24. Coupling of the C1-C20 and C21-C29 parts was achieved by Julia-Kocienski olefination and regio- and stereoselective dihydroxylation of the C20-C21 double bond in the presence of the C4-C5 and C8-C9 double bonds to afford the C1-C29 part of AM3.
