  First Stereocontrolled Synthesis of the (3S,5R,7R,10R,11R)-C1−C13 Fragment of Nystatin A₁

  摘要：

  A convergent stereoselective synthesis of the (3S,5R,7R,10R,11R)-C1-C13 fragment of Nystatin Al is reported in this paper. This fragment contains an all-syn-1,3,5-triol subunit and a syn-1,2-diol moiety. The main features of the synthesis are the enzymatic desymmetrization of a meso diol to obtain an enantiomerically pure syn-4,6-dihydroxy-2-keto-phosphonate, chiral sulfoxide chemistry to prepare an alpha-(R)-hydroxyaldehyde and 2-trimethylsilyl thiazole reagent to synthesize a synthesize a syn-alpha,beta-(R,S)-dihydroxy aldehyde.

  [GRAPHICS]A useful method for the prediction of molar rotation ([Phi]) of syn-2,2-dimethyl-1,3-dioxanes (acetonides) is described. A series of acetonides were prepared by standard methods. A simple additive relationship between the substituents (R, R') and molar rotation was realized.
