A novel palladium‐catalyzed C‐7 selective CH carbonylation of indolines with carbon monoxide for an expedient synthesis of pyrroloquinazolinediones, a structural motif with great potential in biologically active compounds, has been developed. Oxidation of the pyrroloquinazolinedione with 2,3‐dichloro‐5,6‐dicyano‐p‐benzoquinone (DDQ) could easily afford the corresponding indole‐based derivative in
已开发出一种新型的钯催化一氧化碳对二氢吲哚类化合物进行C-7选择性CcarbonylH羰基化反应,以方便地合成吡咯并喹唑啉二酮,这是一种在生物活性化合物中具有巨大潜力的结构基序。用2,3-二氯-5,6-二氰基对苯醌(DDQ)氧化吡咯并喹唑啉二酮可以轻松获得相应的基于吲哚的衍生物,收率很高。
