  Efficient lipase-catalyzed kinetic resolution of 4-arylmethoxy-3-hydroxybutanenitriles: application to an expedient synthesis of a statin intermediate

  摘要：

  The kinetic resolution of 4-arylmethoxy-3-hydroxybutanenitriles was investigated by lipase-catalyzed transesterification in organic solvents. A high enantio selectivity was obtained via reaction with vinyl acetate in a mixed solvent (n-heptane/acetonitrile 1:1), which was catalyzed by the lipase from Artgribacter sp. A better selectivity was demonstrated when the number of substituents on the aryl ring increased. (S)-4-Arylmethoxy-3-hydroxybutanenitriles can be obtained with enantiomeric excesses of up to 98.0% by this method. Furthermore we have developed a novel route to synthesize tert-butyl (S)-6-benzyloxy-5-hydroxy-3-oxohexanoate, a key intermediate for the preparation of HMG-CoA reductase inhibitors (statins).

  cyanide-opening reaction of epoxide with TBAF and TMSN, in THF or TBAF and TMSCN in MeCN occurred regioselectively to afford β-hydroxy azides and cyanides in good yield. These hypervalent silicates have been shown to be highly effective as nucleophilic azide and cyanide donors under mild conditions. This methodology has been applied to the preparation of statine.

  环氧化物与 TBAF 和 TMSN 在 THF 或 TBAF 和 TMSCN 在 MeCN 中的叠氮化物和氰化物开环反应区域选择性地发生，以良好的收率提供 β-羟基叠氮化物和氰化物。这些高价硅酸盐已被证明在温和条件下作为亲核叠氮化物和氰化物供体非常有效。该方法已应用于他汀的制备。
