Investigations have been undertaken into the synthesis of chiral derivatives of 1, 4, 7- triazacyclononane and 1, 7-diaza-4-oxacyclononane that incorporate the C2-symmetric (R, R)-1, 2-diaminocyclohexane backbone. The target ligands 17a and 17b have been prepared as their hydrochloride salts, the latter of which has been characterized by single crystal X-ray diffraction revealing an extensively hydrogen bonded polymeric network in ...
