  The Enantioselective Formal Synthesis of (+)-Avenaciolide and (+)-Isoavenaciolide from Tri-O-acetyl-D-glucal Using a Ring Contraction Reaction as the Key Step

  摘要：

  We describe a formal synthesis of (+)-avenaciolide and (+)-isoavenaciolide starting from methyl tri-O-acetyl-D-glucal. The key steps are a ring-contraction reaction of compound 8 to give the bicycle 6, and the oxidation of the diol 9 to the bis-lactone framework.
