A winning combination: Resveratrol derivatives incorporating a chroman moiety of vitamin E were constructed, resulting in the remarkable enhancement in tris(2,4,6‐trichloro‐3,5‐dinitrophenyl)methyl radical (HNTTM.)‐scavenging activity as compared with the parent molecules (see scheme). Reaction kinetic analysis, oxidative product identification, and redox potential determination demonstrate that the
一个成功的组合:构建了一种白藜芦醇衍生物,其中掺入了维生素E的苯并二氢吡喃部分,与三(2,4,6-三氯-3,5-二硝基苯基)甲基自由基(HNTTM 。)相比,清除活性显着提高。母体分子(参见方案)。反应动力学分析,氧化产物鉴定和氧化还原电势测定表明,该反应受顺序质子损失电子转移(SPLET)机制控制。
