A practical and effective approach towards the synthesis of 3-heteroaryl-4H-chromen-4-ones by the oxidative [1,2] rearrangement of the respective 2-heteroaryl chroman-4-ones using thallium(III) p-tosylate is presented. The oxidative rearrangement of α- and β-naphthyl and thiophene substituents behaves like aryl groups; However, pyridyl substituents gave only dehydrogenated products.
通过使用对甲苯磺酸铊 (III)对各自的 2-杂芳基 chroman-4-ones 进行氧化 [1,2] 重排来合成 3-heteroaryl-4 H -chromen-4-ones的实用且有效的方法是提出了。α-和β-萘基和噻吩取代基的氧化重排表现得像芳基;然而,吡啶基取代基仅产生脱氢产物。
