Abstract
Two enantiomeric novel chiral stationary phases (CSPs) R-3-Amide-BINOL CSP (CSP-1) and S-3-Amide-BINOL CSP (CSP-2) were prepared using (R/S)-1,1'-bi-2-naphthol (BINOL) derivatives as chiral selectors. The structure of CSPs was characterized by nuclear magnetic resonance, scanning electron microscope and elemental analysis. Four chiral solutes were selected under normal phase HPLC conditions to evaluate the chiral separation ability of the two novel CSPs. The effects of mobile phase and acidic additives on enantiomeric separation were investigated. The combination of molecular docking simulation and experimental data has elucidated the crucial role of hydrogen bonds and π-π interactions formed between the analyte and CSP in chiral recognition, and different configurations of CSP can cause enantiomeric elution sequence reversal, indicating that the configuration of chiral selectors in CSP has a significant impact on chiral recognition ability.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
