The “Electrophilic” trichloromethyl radical was introduced directly into the model purine compound, caffeine, leading to products 2 and 3 (the former being smoothly converted to the corresponding carboxy ester derivative) and to the unexpected C-5 substituted title compound 4.
将“亲电子的”三氯甲基基团直接引入模型嘌呤化合物咖啡因中,从而生成产物2和3(前者可以平稳地转化为相应的羧基酯衍生物)和出乎意料的C-5取代的标题化合物4。
