A synthesis of [H-3(2)]-(R, R)-1,2-diaminocyclohexaneoxalatoplatinum(II), [H-3(2)-Oxaliplatin, 2, is described. rac-trans-4-Cyclohexene-1,2-dicarboxylic acid diethyl ester, 6, was converted to rac-trans-1,2-diaminocyclohex-4-ene, 7, by modification of known chemistry aimed at avoiding reported hazards. Resolution of the diamine, 7, with L-(+)-tartaric acid afforded the (R,R)-1,2-diaminocyclohex-4-ene, 8, which was converted to the (R,R)-1,2-bis(tert-butoxycarbamino)cyclohex-4-ene, 10, and tritiated to yield [H-3(2)-(R,R)-1,2-bis(tert-butoxycarbamino)cyclohexane, 11. Hydrolysis of 11 afforded [H-3(2)]-(R,R)-1,2-diaminacyclohexane, 12, which was converted to the desired [H-3(2)]-(R,R)-1,2-diaminocyclohexaneoxalatoplatinum(II), [H-3(2)]-Oxaliplatin, 2.
