carried out in diethyl ether without dehydration, and C–H activation was assisted by the directing anionic nitrogen of the aniline-derived amide. Following the allylation, a domino cycling synthesis of 3,4-dihydroisoquinolin-1(2H)-ones with N-bromosuccinimide (NBS) through intramolecular aminobromination of the introduced double bond was achieved.
用烯丙基溴在室温下开发了 RhIII 催化的缺电子芳烃、杂芳烃和烯烃的 C-H 烯丙基化反应。反应在乙醚中进行,不脱水,苯胺衍生酰胺的导向阴离子氮有助于 C-H 活化。在烯丙基化之后,通过引入的双键的分子内氨基溴化,实现了 3,4-二氢异喹啉-1(2H)-酮与 N-溴代琥珀酰亚胺 (NBS) 的多米诺循环合成。
