A method for intramolecular sp2 C–H oxidative arylation of unactivated cyclic olefins has been developed to access spiro-dihydroquinoline and octahydrophenanthrene derivatives in a straightforward and efficient manner. Bearing picolinamide as a directing group, the alkenyl anilines cyclized to afford spiro-dihydroquinolines in moderate to excellent yields via direct oxidative arylation, while the alkenyl
已开发出一种用于未活化环烯烃的分子内sp 2 C–H氧化芳基化的方法,以一种直接有效的方式获得螺二氢喹啉和八氢菲衍生物。链烯基苯胺以吡啶啉酰胺为导向基团,环化后可通过直接氧化芳基化反应以中等至优异的收率得到螺-二氢喹啉,而链烯基苄胺则通过顺序氧化芳基化和双乙酰氧基化反应以中等收率提供了八氢菲衍生物。
