palladium-catalyzed, norbornene-mediated intermolecular dehydrogenative annulation approach for the synthesis of 6-fluoroalkyl-phenanthridines from aryl iodides and fluorinated imidoyl chlorides, which are important structural motifs for bioactive molecules, is reported. Fluorinated imidoyl chlorides served as a new type of electrophilic reagent in the Catellani-type reaction, which, in turn, could
报道了一种新颖的钯催化,降冰片烯介导的分子间脱氢环化方法,该方法可从芳基碘和氟化亚氨酰氯合成6-氟烷基菲,这是生物活性分子的重要结构基序。氟化亚氨酰氯是Catellani型反应中的一种新型亲电子试剂,而后者又可以很容易地由各种苯胺和氟化羧酸制得。进行了对照实验以研究该反应的机理。这种转换是可扩展的,并且可以容忍各种各样的功能组。
