Toward the Total Synthesis of Goniodomin A, An Actin-Targeting Marine Polyether Macrolide: Convergent Synthesis of the C15−C36 Segment
摘要:
Stereoselective convergent synthesis of the C15-C36 segment of goniodomin A, an actin-targeting marine polyether macrolide natural product, has been achieved. The present synthesis features palladium(0)-catalyzed, copper(I)-mediated Liebeskind-Srogl cross-coupling as the fragment assembly process.

A stereocontrolled convergent synthesis of the C15-C36 segment of goniodomin A, a potent anti-angiogenic marine polyether macrolide, has been achieved using Stille-type cross-coupling reaction of a vinylstannane and a thioester as a key segment assembly process.

Assignment of the Absolute Configuration of Goniodomin A by NMR Spectroscopy and Synthesis of Model Compounds
The complete absoluteconfiguration of goniodomin A, an actin-targeting polyether macrolide isolated from the marine dinoflagellate Alexandrium hiranoi, was established from analysis of ROESY experiments and coupling constants, synthesis of suitable model compounds for NMR spectroscopic comparisons, degradation experiments, and correlation with synthetic reference compounds.
