| Outline of Final Research Achievements |
We carried out the synthetic studies on amphidinol 3, an antifungal polyene-polyol compound isolated from marine dinoflagellate amphidinium klebsii. Although many researchers have been concentrated on the synthetic studies of amphidinol 3, total synthesis of amphidinol 3 has not yet been achieved.
We synthesized the C43-C67 part of amphidinoil 3 and its C51 diastereomer. Through the comparison of their 1H and 13C NMR spectra with those of natural amphidinol 3, we concluded the stereochemistry at C51 should be revised.
We also established the synthetic route for the three requisite parts, i.e., polyhydroxy part (C1-C29), bis-THP part (C30-C52), and polyene part (C53-C67). We are now trying to unite these parts to complete the total synthesis of the proposed structure of amphidinol 3.
