2II-VII, 3I-VII, 6I-VII-Icosa- O -acetyl-2I-deoxy-cyclomaltoheptaose

摘要

Deoxygenation of a secondary hydroxy group on ???2-cyclodextrin was conducted to prepare the title compound 2II-VII, 3I-VII, 6I-VII-icosa- O -acetyl-2I-deoxy-cyclomaltoheptaose. The synthetic procedure comprised a two-step reaction?￠????phenoxythiocarbonylation and Barton-McCombie deoxygenation. The synthesized compound was characterized by 1 H-NMR, 13 C-NMR, HRMS, and elemental analysis.
