1-nitrocodeine was reduced to 1-aminocodeine, a key precursor for the synthesis of the azo derivative and several hydrazones. Structures of both 1-nitrocodeine and 1-aminocodeine were unequivocally determined by single-crystal X-ray analysis. The reported preliminary synthetic study lays the groundwork for the synthesis of modified codeine derivatives with potential biological activity.
描述了在温和的反应条件下使用五水硝酸铋对可待因进行的第一次硝化反应。生成的 1-硝基可待因被还原为 1-氨基可待因,这是合成偶氮衍生物和几种腙的关键前体。1-硝基可待因和 1-氨基可待因的结构均通过单晶 X 射线分析明确确定。报告的初步合成研究为合成具有潜在生物活性的修饰可待因衍生物奠定了基础。
