A Ni(0)/chiral N-heterocyclic carbene (NHC) catalyzed enantioselective and intermolecular [2+2] cycloaddition of α,β-unsaturated carbonyl compounds with conjugated enynes was investigated to produce enantioenriched cyclobutenes (up to 89% ee). The present

Eight new N-heterocyclic carbenes (NHCs) featuring substituted naphthyl side chains were synthesized. These molecules are present in solution as a stable mixture of anti and syn conformers. Through careful tuning of the substituents on position 2 and 2,7
