Synthesis of the C19 through C27 segment of okadaic acid using vinylogous urethane aldol chemistry: Part III

The synthesis of the C-19 through C-27 segment of the marine natural product okadaic acid was accomplished employing a highly enantio- and diasteroselective aldol coupling reaction of a chiral vinylogous urethane lactone enolate. The remainder of the carb
