The oxidation of purpurogallin in alkaline solution by oxygen and hydrogen peroxide is described. It is shown that initial attack on the purpurogallin anion is by oxygen (not hydrogen peroxide), producing a radical ion. This species is oxidised to, and exists in equilibrium with, purpurogalloquinone, which may undergo three separate reactions, two with hydrogen peroxide and one with solvent.
描述了紫杉醇在碱性溶液中被氧气和过氧化氢氧化的方法。结果表明,对紫嘌呤没食子酸酯阴离子的初始攻击是由氧(不是过氧化氢)产生的自由基离子。该物质被氧化为紫嘌呤半乳糖醌并与之平衡存在,其可能会经历三个单独的反应,两个与过氧化氢反应,另一个与溶剂反应。
