Abstract
La La Ligand! Lanthanum(III) complexes incorporating enantiopure PyBOX ligands are suitable catalysts for the enantioselective trifluoromethylation of β-oxo esters in the presence of hypervalent iodine Togni reagent. DFT calculations reveal that the enantioselectivity of the reaction stems from the rigid coordination pattern around the metallic center that results in the efficient blockage of one of the prochiral faces of the intermediate LaIII enolate. More information can be found in the Communication by F. P. Cossío, A. Vallribera, et al. on page 8214.
