An efficient synthesis of (Z)-α-fluorochalcones via the palladium-catalyzed cross-coupling reaction of (Z)-α-fluorocinnamoyl chloride with boronic acids
An efficient synthesis of α-fluorochalcones (1,3-diphenyl-2-fluoroprop-2-en-1-one) based on the Suzuki–Miyaura palladium-catalyzed cross-coupling reaction of arylboronic acids with α-fluorocinnamoyl chlorides in the presence of Cs2CO3 in toluene is described. This approach allows the synthesis of fluorinated analogues of functionalized natural chalcones.
在存在的情况下,基于铃木-宫浦钯催化的芳基硼酸与α-氟肉桂酰氯的交叉偶联反应,可高效合成α-氟代查耳酮(1,3-二苯基-2-氟代丙-2-烯-1-酮)描述了甲苯中Cs 2 CO 3的含量。这种方法可以合成功能化天然查耳酮的氟化类似物。
