METHOD FOR PRODUCING AN ARENE WITH AN AROMATIC C-N BOND ORTHO TO AN AROMATIC C-O BOND
-
Paragraph 0429; 0431; 0433, (2017/03/28)
A method for producing an arene with an aromatic C—N bond ortho to an aromatic C—O bond from a hydroxy arene comprising said aromatic C—O bond is provided. This method comprising the steps a) ortho-oxygenating the hydroxy arene to produce an ortho-quinone, b) condensating the ortho-quinone with a nitrogen nucleophile to generate a compound of Formula (IVa) or (IVb), and c) allowing 1,5-hydrogen atom shift of the compound of Formula (IVa) or (IVb), thereby producing arenes with a C—N bond ortho to a C—O bond of Formula (Va) and (Vb), respectively:
