KF/Al<sub>2</sub>O<sub>3</sub>as a Highly Efficient, Green, Heterogeneous, and Reusable Catalytic System for the Solvent-Free Synthesis of Carboacyclic Nucleosides via Michael Addition Reaction
Abstract KF/Al2O3 acts as an efficient catalytic system for the synthesis of carboacyclic nucleosides via Michaeladdition of pyrimidine and purine nucleobases to α,β-unsaturated esters under solvent-free and microwave conditions. Using this method, the title compounds are produced in good to excellent yields and short reaction times.
