CD capillary electrophoresis methods were developed for complete enantiomeric and diastereoisomeric separations of a series of ten dihydropyridone analogues, of which eight were neutral, one was anionic, and one was cationic. Ten different systems comprising one or two CDs were found to successfully separate the isomers thanks to a screening approach. Among the tested CDs, highly sulfated‐γ‐CD (HS‐γ‐CD), either in a single or in a dual system, in a phosphate buffer using capillaries dynamically coated with polyethylene oxide, and SBE‐β‐CD, either in a single or in a dual system, in a borate buffer using uncoated capillaries, were the most selective selectors. The effects of different parameters such as the nature and concentration of the CDs, nature and concentration of the buffer, and voltage were examined. The precision and LODs and limits of quantification were evaluated for the optimized methods.
