Corrigendum: Metal-Free Annulation of Arenes with 2-Aminopyridine Derivatives: The Methyl Group as a Traceless Non-Chelating Directing Group
In this Communication, the structures of products 5 in Scheme 3 and intermediate 20 in Scheme 4 are incorrect with regard to the position of the substituent (R2) on the imidazole-fused aromatic ring. The same mistake also occurs in the table-of-contents picture and for the structures of products 5 in the Supporting Information; these must be corrected accordingly. Corrected versions of Scheme 3, the structure of intermediate 20, and the table-of-contents picture are provided below.
Scope of application of the methyl-directed reaction. Reaction conditions: 4 (0.2 mmol), 2 (1.0 mmol), PhI(OAc)2 (0.6 mmol total; added in 0.2 mmol portions every 6 h) in HFIP at 40 °C for 18 h. [a] PhI(OAc)2 (0.8 mmol) used, reaction time 24 h.
The authors apologize for any confusion or inconvenience this error may have caused.0
