  A novel and efficient stereoselective synthesis of the southern part of pamamycin-607

  摘要：

  The C1'C11' portion of the antibiotic pamamycin-607 Was synthesized from the enantiomerically pure hydroxy acetate 3, readily available by enzymatic transesterification of the corresponding diol with vinylacetate. This synthesis entailed a series of stereoselective transformations: the absolute configurations of C-6' and C-8' were fixed by an aldol condensation followed by an anti-reduction of the resulting beta-hydroxyketone. The configurations of the last two asymmetric centers C-2' and C-3' were controlled by a novel highly diastereoselective intramolecular cyclization catalyzed by fluoride ions.
