  Synthesis of the C29–C37 segment of spongistatin 1

  摘要：

  Starting from racemic 2 alpha-methyl-8-oxabicyclo[3.2.1]oct-6-en-3-one the spongistatin E segment has been prepared in nine steps (2.3 steps per stereogenic center) with umpolung of anomeric reactivity at C37. This 3,5-syn-diol sequence completes our methodology to all stereoisomers of 3,5,7-trihydroxy heptanoic ester building blocks functionalized for alpha-oxyanion chemistry.
