  Sequential application of stereoselective syn-oxidation methodologies to natural product synthesis: A potentially biomimetic approach to the C12–C21 bistetrahydrofuran region of monensin

  摘要：

  The preparation of an all-Z-triene corresponding to an acyclic premonensin triene is described. In analogy to the Townsend syn-oxidative cyclization hypothesis for natural product biosynthesis, a sequence of regioselective and enantioselective syn-dihydroxylation of the triene, cis-selective syn-oxidative cyclization of the diol-diene, and trans-selective syn-oxidative cyclization of the remaining hydroxyalkene gives the correct stereochemical pattern corresponding to the C and D ring tetrahydrofurans of monensin.
