Synthesis of the C28 through C38 segment of okadaic acid using vinylogous urethane aldol chemistry: Part IV

The synthesis of the C-28 through C-38 segment of the marine natural product okadaic acid was accomplished employing a highly enantio- and diasteroselective aldol condensation reaction of a chiral vinylogous urethane enolate. The stereocenter at C-29 was addressed utilizing a diastereoselective hydroboration reaction.
