    Furans from Novel [3 + 2] Photocycloaddition of Alkenes to 2-(1-Alkynyl)cyclohexenones
    摘要:
    Photocycloaddition of 2-alkynyl-substituted cyclohexenones 8c-11c with isobutylene (2) and tetramethylethylene (3a) leads to tricyclic furans 15a-18a and 15b-17b; respectively, in gas chromatographic yields of similar to 90%. A suggested mechanism for this novel-process is shown in eq 2. Tetramethoxyethylene (3b) gives only oxetanes 22 and 23, and the 3-methyl-substituted ketone 12c fails to react with 2 and 3a,b. tert-Butylethylene gives [2 + 2] adduct 24 with 10c.

  • Access to functionalized alkynylcyclopropanes <i>via</i> reductive radical-polar crossover-based reactions of 1,3-enynes with alkyl radicals
    作者:Beibei Zhang、Junfei Luo、Yewen Fang

    radical-polar crossover process as a strategy, protocols dealing with the preparation of functionalized alkynylcyclopropanes have been successfully developed via the reactions of 1,3-enynes with alkyl radicals. In addition to redox-neutral photocatalysis, nickel catalysis with zinc as the reductant is also an alternative to enable reactions of 1,3-enynes with redox-active N-hydroxyphthalimide esters
    在此,使用基于单电子转移还原的自由基-极性交叉过程作为策略,通过1,3-烯炔与烷基自由基的反应成功开发了制备功能化炔基环丙烷的方案。除了氧化还原中性光催化,以锌为还原剂的镍催化也是使 1,3-烯炔与氧化还原活性N-羟基邻苯二甲酰亚胺酯反应的替代方法。炔基环丙烷的合成应用也得到了证明。

    1-alkynyl-7-oxabicyclo[4.1.0]heptan-2-ones 3a–c and 4a–c, respectively. The 3-unsubstituted bicyclic epoxy ketones 3a, 3b, and 4a, 4b react further with H2O2/NaOH, undergoing ring contraction and (formal) decarbonylation to give 2-alkynylcy-clopent-2-enols 5a, 5b, and 6a, 6b, respectively. Epoxy ketones 3 are also obtained under neutral conditions on irradiation (λ = 350 nm) of cyclohexenones 1 in air-saturated
