A formal total synthesis of didemniserinolipid B was developed by employing a regioselective metal-mediated 6-endo-dig alkynol-cycloisomerization reaction. Two routes for the synthesis of key Burke's intermediate have been developed. Our initial approach involved the introduction of a C17-alkynol followed by Pd-mediated cycloisomerization and then coupling with the serinol unit prior to the introduction
