concise, modular and efficient one‐pot approach to diversely functionalized heterocycles, as exemplified for 3,10‐diaryl 10H‐phenothiazines, 3,9‐diaryl 9H‐carbazoles, and 1,5‐diaryl 1H‐indoles, in high yields starting from simple staring materials. Moreover, this one‐pot reaction is a sequentially palladium‐catalyzed process that does not require additional catalyst loading after the first coupling
连续多组分反应中Suzuki偶联和Buchwald-Hartwig胺的串联反应为各种官能化的杂环打开了一种简洁,模块化且有效的一锅法,例如3,10-二芳基10 H-吩噻嗪,3,9-二芳基9 H-咔唑和1,5-二芳基1 H-吲哚从简单的凝视材料开始就可以高收率。此外,该单釜反应是钯顺序催化的过程,在第一步偶联步骤之后不需要额外的催化剂负载量。
