or by regioselective Fe-catalysed cross-coupling of 2,6-dichloro-9-methylpurine with methylmagnesium chloride, followed by amination. Both the title purinium salts and the purine intermediates were studied by 15N NMR, and one example of the purinium salts also by X-ray diffraction. None of the compounds exerted significant cytostatic activity. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany
通过相应的 2-氨基-6,7-二甲基嘌呤的季铵化制备了三个新的未取代或 N-甲基化的 2-氨基-6,7,9-trimethylpurinium iodides 衍生物。这些中间体是通过 Pd 催化的 2-氨基-6-氯-9-甲基嘌呤与三甲基铝的交叉偶联合成的,或者是通过区域选择性 Fe 催化的 2,6-二氯-9-甲基嘌呤与甲基氯化镁的交叉偶联合成的,然后通过胺化。标题嘌呤盐和嘌呤中间体均通过 15N NMR 进行研究,并且嘌呤盐的一个实例也通过 X 射线衍射进行了研究。没有一种化合物具有显着的细胞抑制活性。(© Wiley-VCH Verlag GmbH & Co.
