| Popis | The chemical shift anisochrony of the fluorine signal for the enantiomerically enriched (3S,4R)-4-(4-fluorophenyl)-3-hydroxymethyl-1-methylpiperidine was induced in the presence of S-Mosher acid and its magnitude varied with the enantiomeric purity of 1a. Very low quantities of an enantiomeric impurity 1b, ranging typically from 0.2 to 1%, were evaluated by comparing peak areas of 1b with those of 13C satellite signals that were deconvoluted using an automatic Lorentzian line fitting. |
