7-substituted derivatives, 2) that the aminomethyl derivative of S6-acetyloxylmethyl-6-MP was a 9-derivative, 3) that the hydroxymethyl derivative of 6-MP was a mixture of 7-substituted and S6,3-disubstitu-ted derivatives, and 4) that the hydroxymethyl derivative of S6-pivaloyloxymethyl-6-MP was a 9-substituted derivative. In addition, a previously unreported dialkyl derivative of 6-MP VI was isolated
通过6-巯基嘌呤(I)(6-MP)和S 6-酰氧基甲基-6-MP的不稳定的氨基甲基和羟甲基衍生物已经通过与乙酸酐反应而转化为稳定的乙酰氧基甲基衍生物。反应产物的分析以及它们的'H nmr光谱和hplc色谱图与已知结构的乙酰氧基甲基衍生物的比较表明,1)6-MP的氨基甲基衍生物是7-取代的衍生物,2)S 6的氨基甲基衍生物-乙酰氧基甲基-6-MP为9衍生物,3)6-MP的羟甲基衍生物为7取代的S 6和3-二取代衍生物的混合物,4)S 6的羟甲基衍生物-新戊酰氧基甲基-6-MP是9-取代的衍生物。另外,从其与氨基甲基化剂的反应中分离出先前未报道的6-MP VI的二烷基衍生物并进行了表征。VI与乙酸酐反应的1'H nmr光谱和hplc色谱分析表明,VI是1,7-二取代的衍生物。
