    Synthesis of α,β-Unsaturated N-Aryl Ketonitrones from Oximes and Diaryliodonium Salts: Observation of a Metal-Free N-Arylation Process
    摘要:
    An efficient transition-metal-free method for the preparation of alpha,beta-unsaturated N-aryl ketonitrones under mild conditions has been developed. This reaction shows good functional group tolerance for both electron-rich and electron-deficient substituents on both oximes and diaryliodonium salts. Two examples of gram-scale preparations have been realized in good yields. Further transformations of these nitrones to different N-heterocycles have been demonstrated. DFT calculations suggest that N-arylation products are formed by [1,3]-phenyl migration of an O-coordinated oximate complex via a four-centered transition state, while the O-arylation products are formed by [1,3]-phenyl migration of a N-coordinated oximate complex.

    对称取代的二亚苄基丙酮衍生物的合成,表征和非线性光学性质
    摘要:
    我们在这里报告8个D-π-A-π-D型双的非线性光学(NLO)特性。这些二亚苄基丙酮(DBA)衍生物是通过Claisen-Schmidt反应合成的。化合物的特征在于紫外可见,FTIR,1 H NMR,13 C NMR,质谱和粉末XRD。通过在芳环的“对位”和“元”位置取代不同的基团(吸电子和供电子),我们观察到在“对位”位置的取代产生了二次谐波。与文献中报道的其他查耳酮相比,这些化合物还显示出更高的双光子吸收率。这些化合物同时显示出二阶和三阶NLO效应,是光子器件中合理的候选材料。

    The synthesis of three series of curcumin analogues with mono-carbonyl is described. Their in vitro anti-bacterial activities against seven Gram-positive and Gram-negative bacteria were tested and the effect of substituents on the aryl ring and the space structure of the linking strain were discussed. It was observed that part of the derivatives displayed significant activity when compared with curcumin and most of them exhibited activity against the ampicillin-resisted Enterobacter cloacae. Compounds A12, B09, B13, B14 and C09 show remarkable antibacterial activity in vitro. The result showed that heterocycle or long-chain substituents may enhance the activity of curcumin analogues.
    本文描述了三种单羰基姜黄素类似物的合成。对七种革兰氏阳性和革兰氏阴性细菌进行了体外抗菌活性测试,并讨论了取代基对芳环和连接张力的空间结构的影响。观察到,与姜黄素相比,部分衍生物显示出显著的活性,并且大多数衍生物对氨苄西林抵抗的阴沟肠杆菌表现出活性。化合物A12、B09、B13、B14和C09显示出显著的体外抗菌活性。结果显示,杂环或长链取代基可能增强姜黄素类似物的活性。

    (ILs) self-assemble to form supramolecular polymeric clusters/aggregates. The aggregation behavior of ILs influences its activity in the organic synthesis. However, the precise role of ILs in organic reactions is still unknown. It is, therefore, important to comprehend the supramolecular polymeric aggregation behavior of ILs. We are exploring the supramolecular polymeric aggregation behavior of ILs
    离子液体(ILs)自组装形成超分子聚合物簇/聚集体。IL的聚集行为影响其在有机合成中的活性。但是,IL在有机反应中的确切作用仍是未知的。因此,重要的是要理解IL的超分子聚合聚集行为。我们正在使用电喷雾电离质谱(ESI-MS)探索IL的超分子聚合聚集行为。我们已经合成了四个亲水性IL(1-4),并研究了它们的聚集行为及其对碳-碳键形成(Knoevenagel和Claisen-Schmidt缩合)催化活性的影响。在这里,我们表明IL的聚集行为取决于阳离子和阴离子的类型和性质。ESI-MS(-ve)光谱揭示了两种不同类型的聚集,即[C n A n + 1 ] -和[A 2  + H + ] -。我们发现,催化活性随[C n A n + 1 ] -超分子聚集的增加而增加。因此,在IL中获得的最高收率的产品显示出阴离子-阴离子聚集的减少[A 2  + H +] – ESI-MS中的丰度。我们预计我们

    The enantioselective, copper/phosphoramidite-catalyzed 1,4-addition of dialkylzinc reagents to acyclic dienones is described. The products of this reaction, obtained with enantioselectivities of up to 95 %, can be further functionalized by a second conjugate addition, or employed in an enolate trapping, ring-closing metathesis protocol.

    small library of monocarbonyl analogs of curcumin 1a–q was synthesized. Lipophilicity and stability in physiological conditions were both assessed by HPLC-UV, while two different methods assessed the electrophilic character of each compound monitored by NMR and by UV-spectroscopy. The potential therapeutic effect of the analogs 1a–q was evaluated in human colon carcinoma cells and toxicity in immortalized
