  Synthetic Studies on the Polyene Macrolide Antibiotics. Development of syn- and anti-1,3-Diol Subunits and Assembly of the Polyacetate Region of Amphotericin B

  摘要：

  The synthesis of syn- and anti-1,3-diol subunits from thiol ester oxazoline 4 has been described. The key features of these synthetic sequences include the stereodivergent allylation of an asymmetric beta-amino aldehyde (7) and the stereospecific transformation of a vicinal amino alcohol to an epoxide. The resultant diasteromeric silyl-protected epoxy alcohols (10s and 10a) serve as convenient precursors to the isomeric diol aldehyde derivatives 13, 13-ent, and 16. One of these fragments, compound 13, has been exploited in a highly convergent synthesis of the C1-C13 polyacetate segment of amphotericin B.
