摘要：

Michael addition of 1,3-dicarbonyls with various Michael acceptors has been found to be catalyzed by commercially available, user-friendly and recyclable N-phenyl-tris(dimethylamino)iminophosphorane immobilize,] on polystyrene resin (P-BEMP). The reaction does not require anhydrous solvents or inert atmosphere and proceeds smoothly at room temperature leading to the corresponding adducts, which can be conveniently isolate in high yield and with high chemical purity by simple filtration.
