This article presents a synthesis of non-protein amino acids derived from 6- and 8- substituted cyclohexanespiro-5-hydantoins, spiro(adamantane-2',4'-imidazolidine)- 2,5-dione and 3',4'-dihydro-2H,2'H,5H-spiro[imidazolidine-4,1'-naphthalene]-2,5-dione. The target compounds were prepared by an alkaline hydrolysis of the corresponding spirohydantoins with barium hydroxide. The products obtained were characterized by physicochemical parameters, IR , 1H and 13C NMR spectral data.

Synthesis and characterization of new Pt(II) complexes of cyclohexanespiro-5-(2-thiohydantoin) (L1) and cycloheptanespiro-5-(2-thiohydantoin) (L2) are discussed. The new complexes are studied by elemental analysis, IR and 1 H NMR spectroscopy. The free ligands are investigated by UV-Vis, IR, 1 H NMR, 13 C NMR and Raman spectroscopy. The ground-state equilibrium geometries of the ligands L1 and L2 and their complexes with Pt(II) are optimized at the BLYP/CEP-31G theoretical level.
