Highly Efficient Synthesis of Substituted 3,4-Dihydropyrimidin-2-(1<i>H</i>)-ones (DHPMs) Catalyzed by Hf(OTf)<sub>4</sub>: Mechanistic Insights into Reaction Pathways under Metal Lewis Acid Catalysis and Solvent-Free Conditions
In our studies on the catalytic activity of Group IVB transition metal Lewis acids, Hf(OTf)<sub>4</sub> was identified as a highly potent catalyst for „one-pot, three-component„ Biginelli reaction. More importantly, it was found that solvent-free conditions, in contra...
