## Abstract A chiral imidazolidine catalyst was shown to catalyze the highly enantio‐ and diastereoselective domino Michael‐aldol reaction of β‐diketone and β‐ketosulfone derivatives with α,β‐unsaturated ketones to form optically active cyclohexanones having three or four contiguous chiral centers.
