Ipso, meta, and para: Benzoic acid derivatives can be highly regioselectively substituted at the ipso, meta, and para positions. The reaction sequence comprises an alkylative Birch reduction, a 4‐alkylation, a palladium‐catalyzed γ‐arylation, and an oxidative rearomatization (see scheme). All the reactions are robust and experimentally easy to conduct.
本位,间位和对位:苯甲酸衍生物可高度区域选择性的取代的本位,间,和对位的位置。反应顺序包括烷基化的桦木还原,4-烷基化,钯催化的γ-芳基化和氧化性重金属化(请参阅方案)。所有的反应都是可靠的,实验上容易进行。
