additions of heterocyclic compounds, such as indoles, pyrrole, pyrazole, and imidazole, have been demonstrated. Hafnium chloride effectively catalyzed the conjugate addition of indoles to α,β-unsaturatedcarbonyl compounds, and the addition product was obtained in high yield. The reaction of pyrrole was also catalyzed by HfCl4 or ScCl3, and produced 2,6-dialkylated pyrroles up to 99% yields. Furthermore
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 and imidazole gave the corresponding N-adducts in excellent yields.
