Natural phosphate (NP) has been found to be a new and highly efficient heterogeneous catalyst for the synthesis of beta-enaminoesters, by simple condensation of various primary amines with beta-dicarbonyl under solvent-free conditions.

Keywords: Natural phosphate (NP), b-enaminoesters, solvent-free conditions
