摘要：

Some modified α-CD on secondary hydroxyl side were prepared and conformation and configuration of them were studied by COSY, TOCY, and ROESY spectra. These spectra indicated that tosyl group of α-CD-2-OTs directed perpendicular to z-axis of α-CD-3-NH2 and δ-CD-3-His had modified altrose residue with 1C4 conformation. Catalytic activity of α-CD-3-His was over 4 times larger than that of α-CD-6-His. © 1990.
