Abstract: 

An efficient, clean and simple procedure for the Michael addition of phthalimide and saccharin to various a, b-unsaturated esters in the presence of tetrabutylammonium  romide (TBAB) and 1,4-diazabicyclo[2,2,2]octane (DABCO) under solvent-free conditions is described. By this method, the Michael adducts are obtained in good to excellent yields in short reaction times under thermal and microwave conditions.
