radical‐mediated synthesis of dihydronaphthalenones from oxime esters has been developed. By using iron salt as a green and inexpensive catalyst, various α‐aryl oxime esters were transformed into the corresponding dihydronaphthalenones in moderate to good yields with high chemo‐selectivities. The reaction proceeds via 1,5‐hydrogen atom transfer and then intramolecular radical cyclization sequence.
在此,已开发了一种简便的方法,用于由肟酯进行铁催化的自由基介导的二氢萘烯酮的合成。通过使用铁盐作为绿色且廉价的催化剂,各种α-芳基肟酯都可以以中等到良好的收率和高化学选择性转化为相应的二氢萘烯酮。该反应通过1,5-氢原子转移,然后通过分子内自由基环化顺序进行。
