  A Stereocontrolled Formal Asymmetric Synthesis of Pseudodistomin C

  摘要：

  An efficient and stereocontrolled formal asymmetric synthesis of pseudodistomin C has been achieved by employing intramolecular transamidation reaction, exo-methylenation, and highly stercoselective hydroboration. The resulting 2-hydroxymethylpiperidine derivative (15) was further converted into the key intermediate (2) for the synthesis of pseudodistomin C.
