一般描述
(S)-(−)-α-Methylbenzylamine is a chiral derivatizing agent, which is employed for derivatizing enantiomers into diastereoisomers.
应用
(S)-(−)-α-Methylbenzylamine may be used as a chiral derivatizating reagent for the determination of acetyl-D-carnitine (D-AC) in acetyl-L-carnitine (L-AC) using high-performance liquid chromatographic (HPLC) enantioseparation method.

A liquid chromatography stationary phase containing immobilized membranes obtained from a cell line that expresses the human organic cation transporter (hOCT1-IAM) has been used to study the binding of the enantiomers of propranolol, atenolol, pseudoephedrine, and alpha-methylbenzylamine to the immobilized

Enzyme immobilization often improves process economics, but changes in kinetic properties may also occur. The immobilization of a recombinant thermostable (S)-aminotransferase was made by entrapment on calcium alginate-3% (w/v)-and tested with (S)-(-)-(alpha)-methylbenzylamine for acetophenone production. The best immobilization results were

A short, convenient, gram scale protocol has been established to allow facile access to all four stereoisomers of 2-aminocyclobutanecarboxylic acid, each in enantiomerically pure form (ee >99%). Starting from the readily available cis racemate, the procedure combines efficient alpha-phenylethylamine derivative

Enantiomerically pure (R)-(+)-pipecolic acid was synthesized in four steps and 42% overall yield starting from dihydropyran and (R)-alpha-methylbenzylamine. A general short strategy is also described for preparing (S)-proline (47.5% overall yield) and derivatives.
