概要
- 論文の詳細を見る
The regioisomers of bis- and tris[C(6)-<I>O</I>-sulfonylated] α-cyclodextrins were converted in satisfactory yields to the corresponding C(6)-pyridinio derivatives, which afforded the characteristic splitting patterns of <SUP>1</SUP>H NMR signals available for a regioisomer determination. Electrostatic repulsive interactions between the positively charged pyridinio groups play an important role in the remarkable splitting of the <SUP>1</SUP>H NMR signals observed for some regioisomers.
