  Multiple equilibration strategies in synthesis. Stereocontrolled synthesis of polypropionate fragments

  摘要：

  A multiple equilibration strategy as a general approach to asymmetric synthesis has been demonstrated. The generation, multiple equilibration, and manipulation of methyl-substituted 4,10-diketo-1,7-dioxaspiro[5.5]-undecanes has led to the synthesis of polypropionate fragments containing tetrahydropyran rings containing seven contiguous stereocenters in only five steps with complete stereocontrol.
