• Stereoselective Monofluoromethylation of <i>N-tert-</i>Butylsulfinyl Ketimines Using Pregenerated Fluoro(phenylsulfonyl)methyl Anion
  作者：Jun Liu、Laijun Zhang、Jinbo Hu

  DOI：10.1021/ol802226k

  日期：2008.12.4

  Pregeneration of fluoro(phenylsulfonyl)methyl anion (PhSO2CHF-) paves the way for the efficient and highly stereoselective monofluoromethylation of (R)-N-tert-butylsulfinyl ketimines. The stereocontrol mode of the present diastereoselective monofluoromethylation of ketimines is different from the previously known nucleophilic fluoroalkylation of (R)-N-tert-butylsulfinyl aldimines, which suggests that a cyclic six-membered transition state (rather than a nonchelation controlled one) is involved in the current ketimine reaction.
