The oxidative radical cyclization of α-fluoroacetophenones in the presence of olefins offers an efficient access to 2-fluorotetralones. Fluorinated starting materials can be prepared from α-bromoacetophenones. The reaction was optimized with respect to a future application in the synthesis of 18-fluorine labeled compounds, where reaction times are a critical aspect.
在烯烃存在下,α-氟苯乙酮的氧化自由基环化提供了2-氟四氢萘酮的有效途径。氟化原料可以由α-溴乙酰苯制备。针对将来在合成18-氟标记的化合物中的应用进行了优化,其中反应时间是至关重要的方面。
