Rh(I)-catalyzed direct arylation of pyridines and quinolines
Abstract
A Rh(I)-catalyzed direct arylation of pyridine and quinoline heterocycles has been developed. The method provides rapid entry into an important class of substituted heterocycles employing inexpensive and readily available starting materials.
