The tested cyclodextrin was the versatile sulfobutylether- β-CD, used either in a phosphate buffer using capillaries dynamically coated with polyethylene oxide or in a borate buffer using uncoated capillaries. Long-end and short-end modes and concentration variations of chiral selectors allowed finding conditions of complete separation of four out of the six derivatives (i.e., 1, 2, 3, and 4) in short run times, confirming their broad range of applications. To separate the two last compounds, the highly sulfated- γ-CD was examined as chiral selector in acidic phosphate conditions. The enantiomers of the γ-lactam analogues 5 and 6 were baseline resolved with 5.5 and 4%, respectively as concentration in the buffer.Show less >
