  Efficient Medium Ring Size Bromolactonization Using a Sulfur-Based Zwitterionic Organocatalyst

  摘要：

  Catalytic bromolactonization of long-chain olefinic acids resulting in the efficient synthesis of medium-sized lactones is reported using a zwitterionic catalyst and stoichiometric N-bromosuccinimide halogen source. The reaction was found to be more efficient at 0 degrees C than at room temperature, which could be attributed to the temperature dependence of the zwitterionic catalyst.

• Oxygen Effect in the Iodo Lactonization of Unsaturated Carboxylic Acids Leading to 7- to 12-Membered Ring Lactones
  作者：Bruno Simonot、Gerard Rousseau

  DOI：10.1021/jo00099a019

  日期：1994.10

  The reaction of omega-alkenoic acids with bis(sym-collidine)iodine(I) hexafluorophosphate led to (iodomethyl) epsilon-caprolactones in good yields (49-75%) and medium ring iodo lactones in low yields (4-5%). The latter compounds have been obtained after introduction of an oxygen atom in the carbon chain. The position of the oxygen appeared important. This oxygen effect was explained by the stabilization of the intermediate iodonium ion by the oxygen atom.

  日期：1993.1

  Iodo lactonization of 6-heptenoic acid using bis(sym-collidine)iodine(I) hexafluorophosphate in methylene chloride led in high yield to 6-(iodomethyl)-hexanolide while with longer omega-ethylenic carboxylic acids the corresponding lactones were obtained in low yields; however, the presence of an oxygen atom in the carbon chain allowed the formation of medium-ring iodo lactones.
