Cu(OTf)2: a reusable catalyst for high-yield synthesis of 3,4-dihydropyrimidin-2(1H)-ones

Modified Biginelli and Hantzsch reactions were carried using environmentally benign processes. Neat reactants subjected to microwave radiation gave the required products more quickly and in better yields in comparison to traditional methodologies. The observed yields and enhancement in reaction rates are due to the solvent free conditions coupled with the use of microwave radiation.

A novel one pot synthesis of nitrogen containing heterocycles: an alternate methodology to the Biginelli and Hantzsch reactions

An expeditious solventless synthesis of novel Mannich bases of thiobarbiturates and barbiturates using montmorillonite clay under microwaves are herein described. This methodology eliminates the use of excess of solvent during the course of reaction. The reaction time is brought down from hours to minutes along with yield enhancement. The rate enhancement and high yield is attributed to the coupling of MWS with solventless conditions. Further, the role of montmorillonite K-10 clay is studied in the reaction and it is concluded that microwave assisted montmorillonite clay catalyzed reaction is the best in terms of catalysis as well as reaction and yield. All the compounds synthesized were screened for their antifungal activity against A. niger and A. flavus and found to possess good activity.
