different synthetic routes lead (i) by the synthesis of the compound via ortho-bromination of a substituted cyclohexanone followed by reaction with hydroxylamine and reduction by hydrogen, (ii) by addition of azide to cyclohexene mediated by manganese(III) acetate and reduction by hydrogen, or (iii) by trans-dihydroxylation of cyclohexene, and subsequent conversion into the respective mesylate or tosylate
提出了三种不同的途径合成取代的反式-(±)-1,2-环己二胺作为奥沙利铂类化合物的新配体。不同的合成路线导致(i)通过取代环己酮的邻溴化合成化合物,然后与羟胺反应并用氢还原,(ii)通过将乙酸锰(III)介导的叠氮化物加到环己烯中并还原通过氢,或(iii)通过环己烯的反二羟基化,然后转化成各自的甲磺酸酯或甲苯磺酸酯,随后被叠氮化物取代,和在4-甲基-反式的情况下还原-(±)-1,2-环己二胺分别优选在赤道上,主要在轴向上或仅在赤道上或轴向上定向的4-甲基。
