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.

An efficient procedure for the synthesis of some carboacyclic nucleosides via microwave-assisted Michael addition of various nucleobases to α,β-unsaturated esters in the presence of tetrabutylammonium bromide (TBAB) and DABCO is described. Using this method, somepyrimidine and purine nucleobases have been alkylated regioselectively in moderate to high yields and short reaction time.
