A new bulky lipophilic chiral ligand based on 1,2-diaminodiamantane is revealed in both of its enantiomeric forms for the preparation of novel platinum(II) complexes. The R,R-enantiomer shows increased efficacy as compared to cisplatin. The binding of diamondoid-based platinum complexes to nucleotides occurs at similar or faster rate for both isomers compared to cisplatin so that the herein revealed platinum(II) complexes are compounds with high anti-cancerogenic activity .

of cancer. A new bulky, lipophilic, and chiral ligand based on 1,2-diaminodiamantane in both of its enantiomeric forms was employed for the preparation of new platinum(II) complexes with chloride and oxalate ligands. The dichloride complexes have a higher solubility and were evaluated as anti-proliferation agents for human ovarian cancer cell lines A2780 and cisplatin-resistant A2780cis. Its R,R-enantiomer
Abstract The reaction of 1-hydroxydiamantane with elemental bromine leads to consecutive cage opening and re-closure, thereby providing a straightforward approach to the class of previously unknown 1,2-disubstituted diamondoid derivatives. Functional group exchange gave, among others, chiral bidentate ligands 1,2-dihydroxy- and 1,2-diaminodiamantane. The latter was enantioseparated on gram scale with ee >98%
