-
Page/Page column 45-49; 62, (2010/12/31)
The present invention relates to derivatized cyclofructan compounds, compositions comprising derivatized cyclofructan compounds, and methods of using compositions comprising derivatized cyclofructan compounds for chromatographic separations of chemical species, including enantiomers. Said compositions may comprise a solid support and/or polymers comprising derivatized cyclofructan compounds.
A synthesis of (S)-α-(fluorodiphenylmethyl)alkylamines by HF-pyridine treatment of 4-alkyl-5,5-diphenyl-oxazolidinones

Treatment of enantiomerically pure (S)-4-alkyl-5,5-diphenyl-oxazolidinones, themselves derived from appropriate amino acids, with HF-pyridine (Olah's reagent) generated a range of (S)-α-(fluorodiphenylmethyl)alkylamines. These compounds represent a novel range of fluorinated chiral amines. Copyright (C) 2000 Elsevier Science Ltd.
Preparation of Fluoro Amines by the Reaction of Aziridines with Hydrogen Fluoride in Pyridine Solution
Wade, Tamsir N.
, p. 5328 - 5333 (2007/10/02)
Hydrogen fluoride combines regiospecifically with aziridines (1) to give 2-fluoro amines (6) in good yields.Fluorine attack is in all cases completely directed to the most substituted ring carbon or to the benzylic carbon.The results, for benzylic aziridi
