Abstract

The synthesis of two 2-formylquinolines is reported via the Skraup method followed by SeO2 oxidation. Each aldehyde is condensed with (1R, 2R)-diaminocyclohexane and (R)-BINAM, yielding four enantiomerically-pure bis (imine–quinoline) ligands. The neutral ligands are reacted with ZnCl2 to give complexes with bis (bidentate) coordination of ZnCl2 units. X-Ray structural characterization of three complexes shows them to have a single-stranded ...
