Abstract


New and efficient methods have been developed for the synthesis of b-enaminones and b-enamino esters in the presence of a catalytic amount of tris(hydrogensulfato) boron or trichloroacetic acid as highly efficient and heterogeneous catalysts at 120 °C under solvent-free conditions. Both methods are simple, and provide desired products in good yields and short reaction times.
