pubmed-article:16445925 | pubmed:abstractText | Mixtures of hexane-like ethoxynonafluorobutane with alcohols were used as MS-friendly mobile phases for separation and efficient detection of non-UV-active enantiomers and diastereomers using normal-phase HPLC-APCI-MS. Racemic muscone, camphorsulfonamide, camphorsultam, BOC-protected 1-(3-aminopropyl)-2-pipecoline and diastereomeric 2-methylhexanoyl camphorsultams were resolved on Chiralpak AS and AD and achiral Luna CN columns. The responses of UV and APCI-MS detectors were compared under separation conditions studied, with MS detection achieving lowest detectable quantity in the range of 0.5-2 ng per chromatographic peak. The absolute configuration of crystalline derivatives of racemic 2-methylhexanoic acid with (S)-(-)-2,10-camphorsultam was determined by X-ray analysis after their automatic purification by preparative LC-MS. The technique described can be used to purify and determine the absolute stereochemistry of compounds of unknown structure which contain free carboxy group and lack sufficient UV absorbance. | lld:pubmed |
