a chemoselective EtPPh2-catalyzed three-component reaction of aromatic aldehyde, alkyl acrylate, and phthalimide or methyl toluenesulfonamide has been achieved. A variety of highly functional adducts can be generated efficiently in one step within 1–72 h in 38–93% yields. The reaction mechanism is proposed to undergo Morita–Baylis–Hillman reactions of aryl-substituted aldehydes and alkyl acrylates
