Metal‐Catalyzed C(sp2)–H Bond Functionalization of Indolinone‐ and Indanone‐Type Chemical Platforms En Route Toward Late‐Stage Functionalization

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 8, 15 April 2026.
An in‐depth survey dealing with the aromatic C—H bond functionalization of biologically‐relevant scaffolds featuring the indolinone and indanone core is discussed as they are unique aromatic scaffolds that are 1,2‐doubly fused with small five‐membered rings.
