In this article, a photoredox protocol for the synthesis of furans via oxidative coupling of olefin generated in situ from cyclopropyl ketones with ketonic oxygen atom is presented. Moreover, bromination of furans in the presence of overstoichiometric oxidant has been achieved with high regioselectivity.
在本文中,提出了一种光氧化还原方案,用于通过环丙基酮与酮氧原子原位生成的烯烃的氧化偶联来合成呋喃。此外,在化学计量过量的氧化剂存在下,呋喃的溴化反应具有很高的区域选择性。
