An enantioselective nickel(0)-catalyzed reductive three-component coupling between aromatic aldehydes, norbornenes, and silanes affords directly silyl-protected indanol derivatives. A new bulky chiral C2-symmetric NHC (NHC = N-heterocyclic carbene) ligand basing on the 1,2-di(napthalen-1-yl)ethylene diamine backbone allows accessing the annulated products as single diastereoisomers in high enantioselectivity
