decarboxylative conjugated addition of glyoxylic acid acetals with various Michael acceptors, including unsaturated amide, ester, aldehyde, ketone, and nitrile under irradiation. Vinyl pyridine and -aryl styrene are also suitable substrates. The reaction offers various types of acetal products, which are of synthetic significance as protected aldehydes.
我们在本文中报道了在辐照下具有各种迈克尔受体(包括不饱和酰胺,酯,醛,酮和腈)的乙醛酸乙二醛的铱-光氧化还原催化的脱羧共轭共轭加成。乙烯基吡啶和α-芳基苯乙烯也是合适的底物。该反应提供了各种类型的缩醛产物,这些缩醛产物作为被保护的醛具有合成意义。
