two pyrrolidinylidenesulfamido-modified β-cyclodextrins (β-CDs) 3 and 4 were prepared and studied for chiral discrimination of the enantiomers (R)- and (S)-1 of zolmitriptan. The pyrrolidinylidenesulfamido spacer improved the chiral discrimination and binding abilities of these modified cyclodextrins. The hosts 3 and 4 showed higher selectivity for (S)-1.
