  Studies on the Stereochemistry of Theonezolides A-C: Elucidation of the Relative Configurations of 1,3-Diol Moieties of the C-4Å`C-17 Fragment

  摘要：

  Four model compounds having syn and anti 1,3-diol type moieties corresponding to C-8/C-10 and C-14/C-16 positions contained in the C-4 similar to C-17 fragment of theonezolides A-C were prepared. Comparison of their spectral data suggested that the 1,3-diol at C-8/C-10 and the OH/OMe groups at C-14/C-16 positions of theonezolides A-C were both syn.

  A Synthesis of a C1-C7 Building Block for the Enantiomer of Hennoxazole A Utilizing a Regioselective Ring Opening of a Cyclic Acetal

  摘要：

  AC(1)-C-7 building block (4) for the enantiomer of hennoxazole A (1), an antivirus and analgesic active marine natural product, was efficiently synthesized from (S)-malic acid utilizing the following key steps: (1) the stereoselective construction of an anti-1,3-diol, (2) the regioselective ring opening of a cyclic acetal, and (3) the oxidative transformation of the olefin into the ketal of the methyl ketone in a one-pot process.

  The absolute stereochemistry of the C-4 ∼ C-17 fragment of theonezolides was establsihed as 8S, 10R, 14S, 16S on the basis of synthesis of the two diastereomers (4a and 4b) suggested from model studies and comparison of their spectral and optical data with those of natural specimen (4) obtained from ozonolysis of 1 ∼ 3.

  在模型研究和比较的基础上提出了两种非对映体（4a和4b）的合成基础上，酮内酯的C-4〜C-17片段的绝对立体化学被确立为8 S，10 R，14 S，16 S。它们的光谱和光学数据与臭氧分解1〜3获得的天然样品（4）的光谱和光学数据一致。
