✦ Synopsis

Synthesis of Atropisomeric Heterotopic S-Donor Ligands Through Asymmetrization of C2-Symmetry 2,2'-Disubstituted 1,1'-Binaphthalene Derivatives.

-Procedures for the conversion of the C2-symmetric binaphthol (I) into atropisomeric dithiols such as (V) or the corresponding O,S-chelating ligand (IX) are reported. Key steps are the asymmetrization of the dicarbamate (II) through selective removal of one S-carbamoyl group and the asymmetrization of the diol (I) via selective monoacylation. -(FABBRI, D.;
