The decarbonylation of primary, secondary, and tertiary alkyl-substituted acyl radicals has been investigated through photoredox catalysis. A series of quaternary carbons and γ-ketoesters have been directly constructed by the photoredox 1,4-conjugate addition of the corresponding alkyl ketoacids with electrophilic alkenes. And, the tertiary alkyl ketoacids have proved to be good precursors of tertiary
已经通过光氧化还原催化研究了伯,仲和叔烷基取代的酰基的脱羰作用。通过将相应的烷基酮酸与亲电烯烃进行光氧化还原1,4-共轭加成反应,可以直接构建一系列的季碳和γ-酮酸酯。并且,叔烷基酮酸已被证明是叔烷基自由基的良好前体。
