The inclusion interaction between hydroxypropyl‐β‐cyclodextrin (HP‐β‐CD) and 21 2‐aryl carboxylic acids was investigated by UV (ultraviolet) spectrophotometer. The inclusion constant of each 2‐aryl carboxylic acids with HP‐β‐CD was determined by Benesi–Hildebrand's equation. According to our previous work, it was found that a high inclusion constant for inclusion complex formed by a racemate and cyclodextrin...
Four stereoisomeric components were produced during the synthesis of the antidepressant drug (1S, 4S)‐sertraline hydrochloride due to the two chiral carbon centers in its chemical structure, including (1S, 4S), (1R, 4R), (1S, 4R), and (1R, 4S)‐isomer. Stereoselective separation of the target isomer (1S, 4S)‐sertraline from the medicinal reaction mixtures by countercurrent chromatography using hydroxypropyl‐β‐cyclodextrin...
