    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.

  • Gold-Catalyzed [3+2]/Retro-[3+2]/[3+2] Cycloaddition Cascade Reaction of <i>N</i> -Alkoxyazomethine Ylides
    作者:Shoichi Sugita、Norihiko Takeda、Norimitsu Tohnai、Mikiji Miyata、Okiko Miyata、Masafumi Ueda

    A novel cascade reaction has been developed for the synthesis of 2,6‐methanopyrrolo[1,2‐b]isoxazoles based on the gold‐catalyzed generation of an N‐allyloxyazomethine ylide. This reaction involves sequential [3+2]/retro‐[3+2]/[3+2] cycloaddition reactions, thus providing facile access to fused and bridged heterocycles which would be otherwise difficult to prepare using existing synthetic methods. Notably
    基于金催化生成的N-烯丙氧基甲亚胺叶立德,已开发出一种新颖的级联反应,用于合成2,6-甲基吡咯并[1,2-b]异恶唑。该反应涉及顺序的[3 + 2] / retro- [3 + 2] / [3 + 2]环加成反应,因此可轻松接近稠合和桥接的杂环,而使用现有的合成方法难以制备。值得注意的是,该反应允许有效地构建三个CC键,一个CO键,一个CN键和一个CH键,以及一个CC键,一个OC键的裂解。一次操作中有一个CH键。还描述了N-烯丙氧基偶氮次甲基叶立德的分子间环加成反应以及该产物随后在四氢萘酚合成中的应用。

    Photocycloaddition of 2-(1-alkynyl)cyclohexenones 1 and 2 with alkenes 3 and 4 furnishes tetrasubstituted furans 5–8 as the only isolated products; a suggested mechanism leads from the alkyl propynyl biradical 12 to carbene 13, which then closes to the furan.

    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。
