Regioselective Synthesis Of 1-Benzyl- And L-Methyl-4-Vinylimidazole And Their Reactions With N-Phenylmaleimide

摘要

The regioselective synthesis of 1-benzyl- and l-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.
