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.
