Abstract

Abstract The reactions of unprotected D-glucosamine with N-coordinated, activated amino acid ester ligands (glycine, diglycine, histidine) of platinum(II) and palladium(II) complexes afford cis- and trans- Cl2Pt(NH2CH2CONHR), trans-Cl2Pt(NH2CH2CONHCH2CONHR)2 and Cl2Pd(histNHR)2 (R = sugar residue) as products. 1,2-Diaminocyclohexane reacts with the activated esters of cis-Cl2Pt- (NH2CH2COOH)2, cis-Cl2Pt(triglyOH)2, cis-Cl2Pt(metOH) and cis-Cl2Pd(histOH) to give dinuclear complexes Cl2Pt[(gly)nNHC6H10NH(gly)n]2PtCl2 (n = 1, 3), Cl2Pt(methNHC6H10NHmeth)- PtCl2 and Cl2Pd(histNHC6H10NHhist)PdCl2.
