Cu(OAc)2-catalyzed direct radical C2 arylation of quinoline N-oxide with arylamines
摘要:
A Cu(OAc)(2)-catalyzed synthesis of 2-arylquinoline N-oxides with easily available arylamines is described. The main features of this reaction are mild reaction conditions, high functional-group tolerance, excellent regioselectivity, and good to excellent yields. This procedure is mild, operationally simple, and constitutes a greener approach to the arylation of quinoline N-oxides. (C) 2017 Elsevier Ltd. All rights reserved.
