Catalytic conjugate addition of heterocyclic compounds to α,β-unsaturated carbonyl compounds by hafnium salts and scandium salts
The hafnium chloride (HfCl4) and scandium chloride (ScCl3) catalyzed conjugate additions of heterocyclic compounds, such as indoles, pyrrole, pyrazole, and imidazole, have been demonstrated. Hafnium chloride effectively catalyzed the
Hafnium chloride catalyzed conjugate addition of pyrrole, pyrazole and imidazole to α,β-unsaturated ketones
Pyrrole, pyrazole and imidazole undergo conjugate addition with α,β-unsaturated ketones in the presence of a catalytic amount of hafnium chloride at room temperature. Although the reaction of pyrrole gave 2,5-substituted C-adduct mainly, those of pyrazole
