Studies towards the total synthesis of the cytotoxic marine macrolide Amphidinolide B have been disclosed. Catalytic asymmetric AAC methodology has been applied to efficiently generate the C11- and the C18- stereocenters in the requisite fragments 114 and 120 throughƒnbeta-lactones 102 and 81 respectively.An efficient route to install the C14-C15 trisubstituted alkene was realized through a stannylcupration reaction. The Stille and Suzuki cross-coupling methodologies were investigated for the formation of the C13-C15 diene of amphidinolide B. Iodide 90 was coupled with boronic ester 114 via an efficient Suzuki reaction to form a C7-C20 fragment 115. Fragment was further homologated and coupled to sulfone 65 to complete a C1-C20 synthon of amphidinolide B.
