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.

Synthesis of Okadaic Acid-Tautomycin Hybrid

One of the three spiro-segments in the synthesis of okadaic acid was synthesized under a new heteroconjugate addition strategy. Successive coupling of this spiro-segment with two tautomycin-synthetic segments afforded a hybrid molecule between okadaic acid and tautomycin.

SYNTHESIS OF A MARINE POLYETHER TOXIN, OKADAIC ACID (3). SYNTHESIS OF SEGMENT C.

The title compound was divided into three retrosynthetic segments, A, B and C, by disconnecting two C-C bonds at C-14/15 and C-27/28.Synthesis of the segment C in the optically active natural form starting from a D-glucose derivatives is described.The key
