    Diastereodivergent synthesis of the C8–C18 precursor and C1′–C11′ subunit of pamamycin 607 induced by a chiral sulfoxide group
    摘要:
    A key step in obtaining the C8-C18 and C1'-C11' fragments of pamamycin 607, which differ by the syn- and anti-configuration of one chiral center alpha to the tetrahydrofuran ring, was the chelation controlled E-Z-isomerization of the substituted vinyl tetrahydrofuran intermediate 3a which has so far been obtained only in the more stable E-configuration.

    2-(2-Tetrahydrofurylidene)propionates, usually obtained only in the more stable (E) configuration 1, were efficiently isomerised into their (Z) isomers 2 by use of Lewis acids or metallated bases. The (E)/(Z) isomerisation was governed by different factors (type of chelating agent, nature and steric demand of the α,β-unsaturated group). We demonstrated that judicious selection of the α,β-unsaturated
