Allyloxy-N-(1-benzyl) cinchonidinium bromide was found to be an effective organocatalyst for asymmetric Michael reactions of thiols with various α,β-unsaturated ketones, acids and esters to provide optically active sulphides with high enantiomeric excess (91–100% ee) and chemical yields (up to >98%). The reaction was performed with 2–8 mol % of catalyst in water at room temperature using tetra-n-butyl ammonium fluoride as an additive.
