Synthesis of a Chiral Alkyl-Bridged Bis(catecholamide) Ligand for the Self-Assembly of Enantiomerically Pure Helicates

All articles of this category The chiral bis(catechol) ligand 4 can be synthesized starting with 1,2-bis(2,3-dimethoxyphenyl)ethane ( 1 ) and S -1-phenylethyl isocyanate ( 2 ). An enantiomerically pure binuclear triple-stranded helicate 5 is formed in a spontaneous self-assembly process from ligand 4 and titanium(IV) ions in the presence of potassium carbonate. self-assembly - helicate - stereoselectivity - titanium compound
