Abstract

It is the first time that 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 followed by Michael additions of amides. Our studies indicated that, in combination of EtPPh2, alkyl acrylate also catalyzed this process.
