  A Stereoselective Synthesis of (+)-Herboxidiene/GEX1A

  摘要：

  A stereoselective synthesis of (+)-herboxidiene is described. The convergent synthesis utilized a Suzuki cross-coupling reaction to assemble the key segments. The synthesis of the functionalized tetrahydropyran ring utilized an Achmatowicz reaction as the key step. The synthesis of the C10-C19 segment was accomplished using Brown's crotylboration, asymmetric alkylation, and a stereoselective allylic chlorination reactions.

  A formal synthesis of herboxidiene/GEX 1A is described. This approach demonstrates successful application of the Prins cyclization for the construction of the tetrahydropyran core of the target molecule. The chirality of the side chain has been established through the Sharpless asymmetric dihydroxylation and Evan's alkylation. The olefin cross-metathesis was applied to couple both key fragments.

  The construction of a C10C26 fragment of the 16-membered antitumor macrolide rhizoxin has been achieved in an efficient manner. The central portion of this molecule has been prepared in enantiopure form via an iterative allylstannylation protocol starting with the ester of (R)-lactic acid. The oxazole portion of rhizoxin was attached via a samarium diiodide modified Julia coupling to generate the

• A Total Synthesis of Herboxidiene Methyl Ester

  日期：——

  The total synthesis of the methyl ester, 35, of herboxidiene (1, a.k.a. GEX1A and TAN-1609), a polyketide displaying both herbicidal and anti-tumor activity, is described. The convergent reaction sequence involves, in its closing stages, the union of the phosphine oxide 3 with the aldehyde 21 to deliver, via a Horner-Wittig reaction with accompanying epimerization at C12, compound 33 that after deprotection affords an alcohol, 34, capable of participating in a regio- and diastereo-selective epoxidation reaction to give target 35. Phosphine oxide 3 was prepared via the intramolecular hetero-Michael addition of a secondary alcohol to a tethered and Z-configured acrylate while aldehyde 21 was generated, in the crucial step of the relevant reaction sequence, via an Ireland-Claisen rearrangement reaction.
