| Abstract: | The enantioselective Michael addition of dimethyl malonate to 1,3-diphenylprop-2-en-1-one promoted by a quaternary derived ammonium salt from quinine as a phase transfer catalyst in different ionic liquids, 1-butyl-3-methyl imidazolium hexafluorophosphate, bmim]PF6, 1-butyl-3-methyl pyridinium tetrafluoroborate, bpy]BF4, 1-butyl-3-methyl imidazolium tetrafluoroborate bmim]BF4 as well as in conventional organic solvents was studied. |
