title: Rhodium-Catalyzed/Copper-Mediated Tandem C(sp(2))-H Alkynylation and Annulation: Synthesis of 11-Acylated Imidazo[1,2-a:3,4-a']dipyridin-5-ium-4-olates from 2H-[1,2'-Bipyridin]-2-ones and Propargyl Alcohols.
abstract: A rhodium-catalyzed/copper-mediated tandem C(sp(2))-H alkynylation and intramolecular annulation of 2H-[1,2'-bipyridin]-2-ones with propargyl alcohols for the synthesis of 11-acylated imidazo[1,2-a:3,4-a']dipyridin-5-ium-4-olates is described.
