文摘A concise route to access 5H-imidazo[2,1-a]isoindole heterofused compounds by copper(I)-catalyzed intra- molecular coupling of non-activated aryl bromides with azoles is reported. With CuI as catalyst, 1,10-phenanth- roline as ligand, and K3PO4 as base, the reactions of 1-(2-bromobenzyl)-IH-imidazoles in DMF/o-xylene (I : 1, V : V) at 145 ℃ afford the corresponding substituted 5H-imidazo[2,1-a]isoindoles in high yields via intramolecu- lar C-arylation.
