  • Diastereomers of (RS)-propranolol were synthesized using (S)-levofloxacin-based new chiral derivatizing reagents (CDRs). Levofloxacin was chosen as the pure (S)-enantiomer for its high molar absorptivity (εo  ∼ 24000) and availability at a low price. Its -COOH group had N-hydroxysuccinimide and N-hydroxybenzotriazole, which acted as good leaving groups during nucleophilic substitution by the amino group of the racemic (RS)-propranolol; the CDRs were characterized by UV, IR, (1) H-NMR, high… CONTINUE READING
