Synthesis of diaminodideoxyalditol analogs of cisplatin as antitumor agents

Acyclic vicinal polyol complexes related to cisplatin were synthesized from D-mannitol by stereocontrolled manipulation of the hydroxy groups. Controlled cleavage of a 3,4-diazido hexitol gave the corresponding D-threitol and D-xylitol analogs, which were converted to their diamino platinum complexes. The antitumor activity of these compounds is reported.
