Rhodium‐Catalyzed Regioselective C7‐Olefination of Indazoles Using an N‐Amide Directing Group |
|
| Abstract: | A rhodium‐catalyzed regioselective C−H olefination of indazole is described. This protocol relies on the use of an efficient and removable N ,N ‐diisopropylcarbamoyl directing group, which offers facile access to C7‐olefinated indazoles with high regioselectivity, ample substrate scope and broad functional group tolerance. |
