One route, two cycles: A palladium‐catalyzed intramolecular direct arylation reaction combined with an isomerization step provided a straightforward synthetic route to both indoles and benzofurans (see scheme). Isolation and functionalization of intermediate alkene isomers allowed the formation of variants having substituents remote from the core.
一种途径,两个循环:钯催化的分子内直接芳基化反应与异构化步骤相结合,提供了直接合成吲哚和苯并呋喃的途径(参见方案)。中间烯烃异构体的分离和官能化允许形成具有远离核的取代基的变体。
