  A Mild Multistep Conversion of N-Protected α-Amino Acids into N-Protected β3-Amino Acids Utilizing the Nef Reaction

  摘要：

  Current methods of homologation of alpha-amino acids to beta-amino acids have limitations. To overcome these shortfalls the Nef reaction has been utilized in the multistep synthesis of beta(3)-amino acids from alpha-amino acids. In this approach, N-protected amino aldehydes, easily accessed from alpha-amino acids, were transformed into the N-protected.gamma-amino nitroalkanes. The Nef reaction was then used to smoothly convert the nitroalkanes into the corresponding N-protected beta(3)-amino acids without notable racemization.
