A versatile strategy for the α-substitution of enones through the formal fusion between enones and unactivated alkenes is described. It relies on the formation and use of α-xanthyl-β-hydroxy ketones, which can be considered as synthetic equivalents of the high energy and difficult to tame alkenyl radicals. The process, which can often be accomplished one-pot, could be extended in one case to an α,β-unsaturated
描述了通过烯酮和未活化烯烃之间的正式融合来进行烯酮α-取代的通用策略。它依赖于 α-xanthyl-β-羟基酮的形成和使用,它可以被认为是高能且难以驯服的烯基自由基的合成等价物。该过程通常可以一锅完成,在一种情况下可以扩展到α,β-不饱和酯。
