    Reactive 2-quinolones dearomatized by steric repulsion between 1-methyl and 8-substituted groups
    摘要:
    Usual 1-methyl-2-quinolone (MeQone) derivatives are not reactive because of aromatic property in the heterocyclic ring. On the other hand, 8-substituted MeQones have been proved to be highly reactive, which is caused by steric repulsion between the 1-methyl and the 8-substituted groups. When 1-methyl-3,6,8-trinitro-2-quinolone was treated with potassium (or trimethylsilyl) cyanide, cyanation proceeded at the 4-position regioselectively as a result of cine-substitution. This reaction is initiated with addition of cyanide species, and the cyanoquinolone is formed by the protonation of the resultant anionic intermediate followed by elimination of nitrous acid. The high reactivity was maintained even when one of the nitro groups on the benzene moiety was replaced by a methyl group, which afforded corresponding cine-substituted products upon treatment with potassium cyanide.

    面向多种光催化有氧氧化的共价有机框架
    摘要:
    在可见光驱动的有机转化中,光活性二维共价有机骨架(2D-COF)已成为有前途的多相光催化剂。在此,通过使用二维COFs作为光催化剂,开发了可见光驱动的各种有机小分子的选择性好氧氧化。在该方案中,由于2D-COF-1对分子氧活化具有非凡的光催化能力,因此在非常温和的条件下获得了高效,优异的官能团耐受性的各种酰胺,喹诺酮,杂环化合物和亚砜。反应条件。此外,得益于多相光催化的固有优势,突出的可持续性和易于光催化的可回收性,在按比例放大反应中,有选择地轻松获得了一种药物分子(莫达非尼)和一种氧化芥子气模拟物(2-氯乙基乙基亚砜)。使用自由基猝灭实验和原位ESR光谱进行了机理研究,证实了2D-COF-1在光催化循环中的作用。

    by the deprotonated salicylaldehyde through an energy-transfer pathway. Consequently, the C-C cleaving alkylation reactions of N-hydroxyphthalimide esters proceed smoothly in the presence of as low as 1 mol % of salicylaldehyde under the visible-light irradiation, affording desired alkylation products with up to 99% yields. Application in visible-light induced aerobic oxidation of N-alkylpyridinium
    水杨醛首次被确立为一种有效的可见光光催化剂。与其他简单的醛类似物相比,水杨醛具有从324 nm到417 nm的独特去质子性红移,并导致荧光量子数从0.0368显着增加到0.4632,从而使水杨醛成为可见光(> 400 nm)光催化剂。实验研究表明,反应性自由基是通过去质子化的水杨醛通过能量转移途径使底物敏化而产生的。因此,在低至1mol%的水杨醛存在下,在可见光下,N-羟基邻苯二甲酰亚胺酯的CC裂解烷基化反应顺利进行,以高达99%的产率提供所需的烷基化产物。

    A range of compounds with methyl groups disposed ortho and peri on heteroaromatic frameworks have been prepared, and T1 values and methyl-methyl Overhauser effects measured for them. Most of the n.O.e . Values were ≤6%, but two examples of methyls flanked by two others exhibited values of 9% (6-hydroxy-4,4,5,7-tetramethyl-3,4-dihydro-2H-benzopyran-2-one) and 15% (1,4,5,8,9-pentamethylcarbazole).
