“Induced Fit” in Chiral Recognition: Epimerization upon Dimerization in the Hierarchical Self-Assembly of Helicate-type Titanium(IV) Complexes

Undecided! A titanium(IV) triscatecholate bearing chiral ester groups shows different CD spectra in methanol and DMSO. The observation of different stereoisomers lies in the preferred conformation of the side groups in the monomer and dimer, which leads to different chiral induction in the different...

Zusammenfassung:Undecided! A titanium(IV) triscatecholate bearing chiral ester groups shows different CD spectra in methanol and DMSO. The observation of different stereoisomers lies in the preferred conformation of the side groups in the monomer and dimer, which leads to different chiral induction in the different species.
