EnantiopureTi(IV) complexes bearing pseudo‐C3 aminotriphenolate ligands have been synthesized and characterized. The complexes bearing ortho phenyl groups act as 1H NMRchiralsolvatingagent (CSA) for the stereochemical analysis of a series of sulfoxides. The coordination of a Lewis base coligand (sulfoxide) and the presence of aromatic rings are the key structural factors for the efficiency of
