General description

The kinetic resolution of racemic 2-phenylbutyryl chloride by sterically hindered chiral secondary alcohols has been evaluated. 2-Phenylbutyryl chloride reacts with 4-methoxybenzoyl chloride catalyzed by PdBr(Ph)(PPh3)2 to yield 1-(4-methoxyphenyl)-2-phenyl-2-buten-1-one.

Application

(R)-(-)-2-phenylbutyryl chloride may be employed as chiral reagent for the determination of dopamine and dopamine-derived salsolinol and norsalsolinol in human brain by GC-MS method. Chiral (S)-(+)-2-phenylbutyryl chloride may be used as derivatization reagent for the hydroxyl groups during the GC-MS assay for the enantiomers of 1,2-propanediol, 1,3-butanediol, 1,3-pentanediol and their corresponding hydroxyacids in biological fluids.

Using a solid-phase extraction procedure and a gas chromatographic-mass spectrometric (GC/MS) method the levels of dopamine and the levels of dopamine-derived salsolinol (SAL) and norsalsolinol (NorSAL) were determined in human brain areas involved in the etiology of alcoholism, parkinsonism and

We developed gas chromatographic-mass spectrometric assays for the enantiomers of 1,2-propanediol, 1,3-butanediol, 1,3-pentanediol, and their corresponding hydroxyacids, lactate, beta-hydroxybutyrate, and beta-hydroxypentanoate (3-hydroxyvalerate) in biological fluids. The corresponding ketoacids, acetoacetate and beta-ketopentanoate, can be assayed simultaneously by pretreating the samples with
