NH2OH·HCl reacts with α,β-unsaturated ketones followed by the nucleophile ethylene glycol allowing the synthesis of 2,3-disubstituted 1,4-dioxanes using cesium carbonate as a base under Williamson ether synthesis. This reaction is useful for the synthesis of functionalized 1,4-dioxane having a carbonyl functionality. A variety of 2,3-disubstituted 1,4-dioxanes have been synthesized using these reaction conditions
我们已经观察到NaIO 4和NH 2 OH·HCl的试剂组合与α,β-不饱和酮反应,然后与亲核乙二醇反应,从而允许使用碳酸铯作为碱合成2,3-二取代的1,4-二恶烷在威廉姆森醚合成下。该反应可用于合成具有羰基官能度的官能化1,4-二恶烷。使用这些反应条件已经合成了各种2,3-二取代的1,4-二恶烷。还提出了可能的反应机理。
