## 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.

Allylindium reagents, prepared from excess allylic halide (Br or I) and indium metal, react with α,β-unsaturated ketones and aldehydes to give, after aerobic acidic workup, homoallyl-substituted vinylcyclopropanes. This process was explored and developed after a chance discovery arising from a side
