Highly efficient synthesis of carboacyclic nucleosides catalyzed by zinc oxide in 1-butyl-3-methylimidazolium bromide (ZnO/[bmim]Br)
Michael addition of pyrimidine and purine nucleobases to substituted as well as unsubstituted α,β-unsaturated esters efficiently proceeds in the presence of catalytic amount of zinc oxide in ionic liquid 1-butyl-3-methylimidazolium bromide (ZnO/[bmim]Br) under microwave irradiation to afford carboacyclic nucleosides, as biologically important compounds, in good to excellent yields and in short ...

متن کاملUnusual fluorescein prototropism within aqueous acidic 1-butyl-3-methylimidazolium tetrafluoroborate solution.
Fluorescence emission of the cationic form of fluorescein is observed from dilute aqueous acidic solutions in the presence of ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate which is otherwise observed only from aqueous solutions of very high acidity.

متن کاملNMR study for self-aggregation of 1-butyl-3-methylimidazolium bromide in aqueous solution.
Self-aggregation of 1-butyl-3-methylimidazolium bromide ([bmim]Br) in D(2)O has been investigated using NMR spectroscopy. The (1)H spin-lattice relaxation times (T(1)) of the [bmim](+) increased with the decrease of concentration in the range of 0.1-3.0 mol dm(-3) as expected, however, in contrast, the (1)H-T(1) decreased below 0.1 mol dm(-3). The estimated (13)C-activation energies indicated t...
