An EtPPh2- or PPh3-catalyzed tandem three-component reaction of aldehyde, alkyl vinyl ketone, and amide is developed. Its further application in one-pot syntheses of highly functional alkenes starting from aldehydes, alkyl vinyl ketones, 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)
一个 EtPPh 2- 或者 PPh 3催化醛,烷基乙烯基酮和酰胺的三级串联催化反应。实现了其从醛,烷基乙烯基酮和酰胺开始的一锅合成高功能烯烃的进一步应用。在整个3–29.5 h内,可以以68–99%的产率提供各种各样的高功能性α,β-不饱和酮,且具有高立体选择性(E / Z高达98:2)。
