A range of O-perfluoropyridin-4-yl oximes were successfully utilized in C(sp2)-C(sp3) bond formations of quinoxalin-2(1H)-ones and alkenes, providing facile accesses to a range of functionalized alkylnitriles.

    An efficient synthesis of cyanoalkylated heteroarenes via iron-catalyzed direct C–H cyanoalkylation of heteroarenes has been developed. Structurally diverse cyanoalkyl motifs generated through C–C bond cleavage of cyclobutanone oxime esters have been introduced into quinoxalin-2(1H)-ones, flavone, benzothiazoles, and caffeine in good to excellent yields. Remarkably, less-strained cyclopentanone and

  • Visible-light-driven cyanoalkylation of quinoxalinones using cyclobutanone oxime esters as the radical precursors
    作者:Bin Zhao、Xianqiang Kong、Bo Xu
    DOI:10.1016/j.tetlet.2019.06.059
    日期:2019.8
    We have developed a versatile visible-light-driven cyanoalkylation of quinoxalinones under mild conditions. First, the cyanoalkyl radicals are generated from readily available cyclobutanone oxime esters under blue light irradiation. Then the generated radicals react with heterocycles such as quinoxalinones to give the final cyanoalkylation products. The protocol tolerates a wide range of functional groups. Our cyanoalkylation protocol does not need cyanide-based reagents and also does not need external oxidants. (C) 2019 Elsevier Ltd. All rights reserved.
