  Reverse Cope elimination reactions. 1. Mechanism and scope

  摘要：

  N-4-Pentenyl- and N-5-hexenyl-N-methylhydroxylamine cyclized under mild conditions in a reverse Cope elimination reaction to give 1,2-dimethylpyrrolidine N-oxide and 1,2-dimethylpiperidine N-oxide, respectively. The reaction was shown to be concerted and thermodynamically controlled. The scope of this novel cyclization is discussed, and comparisons are made with the closely related and previously reported cyclization of monosubstituted alkenylhydroxylamines to give cyclic hydroxylamines.

  Direct Catalytic Anti-Markovnikov Hydroetherification of Alkenols

  摘要：

  A direct intramolecular anti-Markovnikov hydroetherification reaction of alkenols is described. By employing Catalytic quantities of commercially available 9-mesityl-10-methylacridinium perchlorate and 2-phenyl-malononitrile as a redox-cycling source of a H-atom, we report the anti-Markovnikov hydroetherification of alkenes with complete regioselectivity, In addition, we present results demonstrating that this novel catalytic system can be applied to the anti-Markovnikov hydrolactonization of alkenoic acids.
