A selective sequence: An enantioselective synthesis (see scheme) of atropisomerically defined p‐terphenyls, as well as tetra‐ and pentaaryl compounds is reported. The synthesis proceeds through sequential atropisomer‐selective electrophilic aromatic substitution and regioselective palladium‐catalyzed cross‐coupling reactions.
选择性序列:报道了对映异构定义的对三联苯以及四芳基和五芳基化合物的对映选择性合成(参见方案)。该合成通过顺序阻转异构体选择性亲电芳香取代和区域选择性钯催化交叉偶联反应进行。
