## Abstract The synthesis of a new, highly efficient __cis__‐ion‐tagged catalyst (**8a**), possessing an amide linkage between the imidazolium tag and the proline ring, is described. This new bench‐stable catalyst has been tested in the classic asymmetric aldol condensation between ketones and alde
