Warfarin was converted into O-perfluoroacyl derivatives and separated into enantiomers by capillary GC with chiral stationary phase of polydimethylsiloxane anchored with S(−)-t-leucine-S(−)-1-phenylethylamide. All the derivatives showed almost complete separation. Especially in the case of O-heptafluorobutyryl derivative, baseline separation could be observed.
华法林被转化成O-全氟酰基衍生物,并通过带有手性固定相(附着有S(-)-叔亮氨酸-S(-)-1-苯乙酰胺的聚二甲基硅氧烷)的毛细管气相色谱法分离为对映体。所有的衍生物都显示出几乎完全的分离。尤其是在O-七氟丁酰基衍生物的情况下,可以观察到基线分离。
