A Pd-catalyzed branch- and enantioselective allylic C–H alkylation reaction has been developed for the rapid assembly of fluorinated quaternary stereogenic centers from allylarenes and prochiral α-fluorinated esters. Using chiral phosphoramidite as ligand and 2,5-diphenylquinone as oxidant, the reaction proceeds smoothly under mild conditions and tolerates a broad scope of substrates, resulting in
钯催化的支链和对映选择性烯丙基 C-H 烷基化反应已被开发出来,用于从烯丙芳和前手性 α-氟化酯快速组装氟化季立体中心。以手性亚磷酰胺为配体,2,5-二苯基醌为氧化剂,反应在温和条件下顺利进行,底物范围广泛,得到具有高收率、对映选择性和区域选择性的α-季氟化酯产物。
