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.

report the synthesis of [6,7,5]-tricyclic compounds containing an oxabicyclo [3.2.1] octane system from 1,6-enyne carbonyl. We also synthesized [6,7,6]-tricyclic compound from 1,7-enyne carbonyl through Au-catalyzed cyclization. The synthesis of oxacyclic compounds using iodine or oxygen is environmentally friendly cyclization methods. Oxacyclic compounds are useful for synthesizing various diterpene
我们报告了 [6,7,5]-三环化合物的合成,该化合物含有来自 1,6-烯炔羰基的氧杂双环 [3.2.1] 辛烷系统。我们还通过 Au 催化环化从 1,7-烯炔羰基合成了 [6,7,6]-三环化合物。使用碘或氧合成氧杂环化合物是一种环境友好的环化方法。氧杂环化合物可用于合成各种二萜生物碱。
