photoredox-catalyzed dicarbofunctionalization of styrenes with oxime esters and CO2 has been achieved. Notably, a series of four-, five-, or six-membered cyclic ketone oximes worked well to furnish a wide range of ε-, ζ-, and η-cyanocarboxylic acids in good yields. Furthermore, a series of γ-keto acids also could be obtained by employing acyclic ketone oxime esters as the carbonyl radical precursor. It provides convergent
已经实现了苯乙烯与肟酯和 CO 2的光氧化还原催化双碳官能化。值得注意的是,一系列四元、五元或六元环酮肟可以很好地以良好的产率提供各种 ε-、ζ- 和 η-氰基羧酸。此外,以无环酮肟酯为羰基自由基前驱体,还可以得到一系列γ-酮酸。它提供了对多种生物学上重要的氰基羧酸和 γ-酮酸的聚合访问。
