概要
- 論文の詳細を見る
Inspection of the proton and carbon-13 nuclear magnetic resonance (^1H- and ^<13>C-NMR) spectra of shikonin (1), cycloshikonin (9) and their derivatives led to the conclusion that, in solution, they exist neither as a semihydroquinone structure nor as tautomeric structures as reported recently, but as the commonly accepted 2-substituted 5,8-dihydroxy-1,4-naphthoquinone structure. Further, these compounds were shown to assume a comformation which allows the C-3 hydrogen and the O-functional group of the side chain to be in close proximity.
