A conformational model of per-O-acetyl-cyclomaltoheptaose (-beta-cyclodextrin) in solution: detection of partial inversion of glucopyranose units by NMR spectroscopy.
The stereochemical features of per-O-acetyl-cyclomaltoheptaose (-beta-cyclodextrin) have been investigated in solution by NMR spectroscopy, and the deviation of functionalised glucopyranose rings from 4C(1) chairs to skew-type conformations has been detected.
