We described hereby an instance of diastereoselective silver-catalyzed 1,3-dipolarcycloaddition of azomethineylides with imine compounds. This new method provided synthetically useful, highly substituted tetrahydroimidazole derivatives with efficiency and high diastereoselectivity. We can conveniently obtain fluorinated dihydroimidazole, imidazole, and diamino esters through simple modification.
