    摘要: One aspect of the present invention relates to a process of making cyclohexane-1,2-di(O)-4,5-di(N) diastereomers which are useful as a synthons for various diastereoisomeric pharmaceutical systems. The present invention also relates to the stereoisomer compounds which are derived from retro- synthetic analysis. In another aspect, the present invention relates to novel antineoplasic Pt(II) complexes derived from the stereoisomers and the processes for making such Pt(II) complexes. Mono- and di-hydroxyl substitution on the cyclohexane ring renders the organoplatinum complex relatively more water soluble, thereby facilitating intravenous administration. The Pt(II) complexes of the present invention are less nephrotoxic than cisplatin and are readily excreted via the kidney due to their enhanced water solubility. In a composition aspect, the present invention encompasses novel pharmaceutical compositions comprising the novel Pt(II) complexes in an amount sufficient to have an antineoplastic effect in an animal or patient.
