Notes:
Various erythro- and threo-configurated dichloro[1-(hydroxyphenyl)-2-phenyl-1,2-ethanediamine]platinum(II) complexes were synthesized with the hydroxy group located in either the 2-, 3-, or 4-position of the phenyl ring (38-40). The diastereoisomeric 1-(3-hydroxyphenyl)-2-phenyl-1,2-ethanediamines (31, 32) and threo-1-(2-hydroxyphenyl)-2-phenyl-1,2-ethanediamine (30) were obtained by reduction of the 1,2-diazidoethanes and subsequent ether cleavage. The configuration of the threo-1,2-diazido-1-(2-methoxyphenyl)-2-phenylethane (5) was elucidated by X-ray analysis. The reduction of the erythro-1,2-diaryl-1,2-diazidoethanes, substituted with a methoxy group in ortho or para position, results in elimination reactions with formation of side products. The desired 1,2-diaryl-1,2-ethanediamines were finally synthesized via either an aziridine derivative 21 or by reduction of the respective dioximes 27, 28. The diamine ligands were converted into the corresponding dichloroplatinum(II) complexes 38 - 40.
