Popis | S-Mosher acid induced chemical-shift non-equivalence in NMR spectra of chiral trans-4-(4-fluorophenyl)-3-substituted-1-methylpiperidines. The magnitude of Dd in 1H and 19F NMR spectra varied with the substituent at position 3 of the piperidine ring. The magnitudes Dd observed for certain protons and for the fluorine in the 4-fluorophenyl group were sufficiently large to allow determination of enantiomeric composition. |
