Abstract

Synthesis and characterization of

15N-labeled and partially

13C-labeled oxaliplatin in a racemic mixture with its S,S enantiomer, (SP-4-2)-[(trans-1R,2R/1S,2S-

15N

2)-cyclohexane-1,2-diamine][(

13C

2)oxalato]platinum(II), is presented.

15N labeling of trans-cyclohexane-1,2-diamine (DACH) was conducted by reacting cyclohexane-1,2-dione with the

15N source (

15N)hydroxylamine hydrochloride. After reduction, trans-(

15N

2)DACH was isolated as a tartrate salt and reacted with K

2[PtCl

4]. Subsequent reaction with (

13C

2)oxalate afforded the final

15N- and

13C-labeled oxaliplatin together with its S,S analog. Detailed characterization was performed by one- and two-dimensional

1H,

13C,

15N, and

195Pt NMR spectroscopy; high-resolution mass spectrometry; and elemental analysis. The reaction behavior towards chloride ions, 5′-guanosine monophosphate, and l-methionine was studied by 1D

1H,

13C, and

195Pt NMR spectroscopy and 2D [

1H,

15N] and [

1H,

195Pt] NMR spectroscopy.
