Rh(III)-catalyzed regioselective hydroarylation of alkynes via directed C-H functionalization of pyridines

Rh(III)-catalyzed C-3 selective alkenylation of pyridine derivatives via hydroarylation of alkynes has been developed. The reaction shows high regioselectivity, high yield and good functional group tolerance, providing a convenient strategy for the synthesis of trisubstituted (pyridin-3-yl)alkenes.
