first time. The reaction is stereospecific and provides fair to quantitative yields of fluoroalkenes. The Mizoroki–Heck reaction starting from more hindered and usually reluctant trisubstituted acrylate, to access tetrasubstituted fluoroalkenes, is also reported. Finally, the use of a three-step synthesis sequence, including Mizoroki–Heck reaction, allows the synthesis of fluorinated analogues of therapeutic
首次报道了无配体的,高效的,钯催化的α-氟代丙烯酸甲酯与芳烃或戊烯碘化物之间的Mazoroki-Heck反应。该反应是立体定向的,并提供了公平至定量的氟代烯烃收率。还报道了从更受阻且通常不愿使用的三取代丙烯酸酯开始的四唑基-希克反应,直至获得四取代的氟代烯烃。最后,使用三步合成序列(包括Mizoroki-Heck反应),可以高产率合成治疗剂的氟化类似物。
