Shafir, Alexandr,Lichtor, Phillip A.,Buchwald, Stephen L.
, p. 3490 - 3491 (2007)
Two complementary protocols for copper-catalyzed arylation of aminoalcohols were developed. Selective N-arylation was accomplished at room temperature using 2-isobutyrylcyclohexanone (a β-diketone) as supporting ligand, while selective O-arylation require
