Performance of a New Hplc Chiral Stationary Phase Derived from N-(3,5-dinitrobenzoyl)-d-α-phenylglycine with a Quinoxaline Branching Unit
نویسندگان
چکیده
A new brush-type HPLC chiral stationary phase (CSP) comprising π-acidic N-(3,5-dinitrobenzoyl)-D-α-phenylglycine chiral units bound to the quinoxaline units of modified γ-aminopropyl silica gel by a 1,2-diaminoethane spacer has been prepared by solid-phase synthesis. To test the CSP attempts were made to separate the enantiomers of twenty-two racemates with different functional groups and the results were compared with those obtained by use of three structurally related chiral stationary phases.

Two new diastereomeric chiral stationary phases (CSPs) based on (+)-(18-crown-6)-2,3,11,12-tetracarboxylic acid as a chiral tethering group and a Π-basic chiral unit such as (R)-1-(1-naphthyl)ethylamine (CSP 1) or (S)-1-(1-naphthyl)ethylamine (CSP 2) were prepared. The two CSPs were applied to the enantiomeric separation of N-(3,5-dinitrobenzoyl)-1-phenylalkylamines and N-(3,5-dinitrobenzoyl)-α...

Background: D-Phenylglycine aminotransferase (D-PhgAT) is highly beneficial in pharmaceutical biotechnology. Like many other enzymes, D-PhgAT suffers from low stability under harsh processing conditions, poor solubility of substrate, products and occasional microbial contamination. Incorporation of miscible organic solvents into the enzyme’s reaction is considered as a solution...
