An EtPPh2- or PPh3-catalyzed tandem three-component reaction of aldehyde, alkylvinylketone, and amide is developed. Its further application in one-pot syntheses of highly functional alkenes starting from aldehydes, alkylvinylketones, and amides is realized. A wide variety of highly functional α,β-unsaturated ketones can be furnished in 68–99% yields with high stereoselectivity (E/Z up to 98 : 2)
