Abstract
Abstract New permethylated mono-6-deoxy-6-pyridin-1-ium and mono-6-deoxy-6-(1-vinyl- 1H-imidazol-3-ium)-α-and-β-cyclodextrin trifluoromethanesulfonate ionic liquids were synthesized from the corresponding permethylated mono-6-hydroxycyclodextrins in a one- pot reaction and solvent-free procedure. Regioselective transformation of native α-and β- cyclodextrins with the use of a bulky tert-butyldiphenylsilyl protecting group afforded the ...
