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. The association constants (Table) and enantioselectivity
制备了两个吡咯烷亚烷基磺酰胺基修饰的β-环糊精(β- CDs)3和4,并进行了手性鉴别佐米曲普坦的对映体(R)-和(S)-1的研究。吡咯烷基亚基磺酰胺基间隔物改善了这些修饰的环糊精的手性鉴别和结合能力。宿主3和4对(S)-1表现出更高的选择性。计算(R)-和(S)-的配合物的缔合常数(表)和对映选择性因子。1个带有β- CD 2 – 4。1 H-NMR研究证实了宿主·客体复合物的形成。
