Abstract
AbstractWe describe the application of a chiral catalytic imidazolium salt derived from trans‐L‐hydroxyproline, the anion being the catalytic entity, as a catalyst for the asymmetric Michael addition. We report the first example of a catalytic Michael addition using this type of catalyst, leading to excellent yields (up to 99 %) and good selectivities (up to 99:1 dr, up to 82 % ee).
