Regioselective C2-arylation of imidazo[4,5-b]pyridines
Macdonald, Jonathan,Oldfield, Victoria,Bavetsias, Vassilios,Blagg, Julian
, p. 2335 - 2347 (2013/04/23)
We show that N3-MEM-protected imidazo[4,5-b]pyridines undergo efficient C2-functionalisation via direct C-H arylation. Twenty-two substituted imidazo[4,5-b]pyridines are prepared and iterative, selective elaboration of functionalised imidazo[4,5-b]pyridin
