概要
- 論文の詳細を見る
The order of acetylation of four hydroxyl groups in the sugar moieties of digitoxin (Ia) was revised to be 4'''→3'''→3''-or 3'-positions by the results of acetyl migration test and cis-glycol test as well as modified controlled polysaccharide degradation method using metaperiodate. Nuclear magnetic resonance (NMR) spectra of several acetates of Ia were examined, and the conformations of digitoxose moieties of Ia were confirmed to be all C1-form as formula XIa from the NMR data and reactiviteis of hydroxyl groups in acetylation.
