  Synthetic Studies on Quinocarcin: Total Synthesis of (.+-.)-Quinocarcinamide via Dipole Cycloaddition of an Azomethine Ylide Generated by NBS Oxidation

  摘要：

  The total synthesis of (+/-)-quinocarcinamide and a formal total synthesis of the antitumor, antibiotic quinocarcin involving a [3 + 2] dipolar cycloaddition reaction is described. The synthesis involves as a key step an NBS oxidation of an allylic tertiary amine to an imminium ion which is converted in situ into an azomethine ylide. Aspects of the ylide formation and a rationale for the regio- and stereocontrol for the cycloaddition process are discussed.
