Alkyl, glycosyl and glycopeptidyl derivatives of 6(I)-deoxy-6(I)-thiou
reidocyclomaltoheptaose, prepared in high yield from either 6'-amino-6
(I)-deoxycyclomaltoheptaose or the corresponding 6(I)-isothiocyanate,
exhibit considerably enhanced water solubilities as compared with the
native beta-cyclodextrin.
