group by oxidation with m-chloroperoxybenzoic acid affording purines 15–18 and their 8-azaanalogs 19–21; these compounds, as crude products, were treated with an amine to yield the corresponding adenines 22–25 or 8-azaadenines 26–31. All reactions were performed under conditions com patible with the possible use of a thiomethyl resin in place of phenylmethanethiol to bind the pyrimidine ring of 1 to a
将适当取代的嘧啶1转化为许多标题化合物。取决于反应温度,通过用苯甲硫醇处理,在1中包含氯原子的亲核取代产生2或3。用胺处理3得到6-苯基甲硫基-N 4-取代的-2-苯基-嘧啶-4,5-二胺4-7。这些嘧啶被转化为2-苯基嘌呤8-11和2-苯基-8-氮杂嘌呤12-14通过在盐酸(或乙酸酐)存在下用原甲酸三乙酯处理,或分别用亚硝酸钾和乙酸处理。上C(6)硫醚函数然后用转化成磺酰基通过氧化米氯过氧苯甲酸,得到嘌呤15-18和它们的8 azaanalogs 19-21 ; 这些化合物作为粗产物用胺处理,得到相应的腺嘌呤22–25或8-氮杂腺嘌呤26–31。所有反应均在与可能使用硫代甲基树脂代替苯基甲硫醇以使1的嘧啶环与固相结合的条件下进行。
