  名称：

  Asymmetric synthesis of (1S,6R,7S,9R)-7,9-bis(tert-butyldiphenylsilyloxy)-3-oxabicyclo[4,3,0]nonan-2-one

  摘要：

  The asymmetric synthesis of (1S,6R,7S,9R)-7,9-bis(tert-butyldiphenylsilyloxy)-3-oxabicyclo[4,3,0]nonan-2-one 1 from (4S)-4-acetoxy-2-methoxycarbonyl-3-methoxycarbonylmethyl-2-cyclopenten-1-one 2 is described in eight steps. Compound 2 was readily prepared from L-malic acid according to a known procedure. The key step of this synthesis is a palladium on charcoal catalyzed hydrogenation of olefinic bicyclic lactone 9.
