Abstract

The regioselective synthesis of 1-benzyl- and 1-methyl-4-vinylimidazole from 4,5-diiodoimidazole is described. Their Diels-Alder reactions with N-phenylmaleimide provide a variety of adducts, including the anticipated enamine and the corresponding aromatized isomer. However, additional products including ene adducts, a bis Diels-Alder adduct and oxidation products were isolated.
