  An Asymmetric Synthesis of (2S,5S)-5-Substituted Azepane-2-Carboxylate Derivatives

  摘要：

  To facilitate a drug discovery project, we needed to develop a robust asymmetric synthesis of (2S,5S)-5-substituted-azepane-2-carboxylate derivatives. Two key requirements for the synthesis were flexibility for elaboration at C5 and suitability for large scale preparation. To this end we have successfully developed a scalable asymmetric synthesis of these derivatives that starts with known hydroxy-ketone 8. The key step features an oxidative cleavage of aza-bicyclo[3.2.2]nonene 14, which simultaneously generates the C2 and CS substituents in a stereoselective manner.
