    The synthesis of heliannuol C, an allelochemical from Helianthus annuus
    摘要:
    The synthesis of the allelochemical heliannuol C I is described by employing a Bargellini condensation and a Claisen rearrangement to install the gem-dimethyl and vinyl functionalities, respectively. A Dieckmann cyclisation of diester 11 enabled the generation of the benzoxepane ring system enshrined in 1. (c) 2006 Elsevier Ltd. All rights reserved.

  • On the Possibility of Tuning Molecular Edges To Direct Supramolecular Self-Assembly in Coumarin Derivatives through Cooperative Weak Forces: Crystallographic and Hirshfeld Surface Analyses

    (lone pair)···π interactions cooperatively take part. The recurring feature of the self-assembly in all the compounds is the appearance of the molecular ribbon through weak hydrogen bonding. These hydrogen bonded ribbons further stacked into molecular layers by π···π forces. The mode of cooperativity of the weak C–H···O and π···π forces is such that they operate in mutually perpendicular directions
    基于取代的香豆素衍生物(四种有机化合物1 - 4)已通过X射线结构研究进行了合成和表征,并对Hirshfeld表面和指纹图进行了详细分析,从而有助于比较分子间相互作用在构建不同的超分子体系结构中的作用。X射线研究表明,在分子堆积中,C·H···O,π···π和羰基(孤对)···π相互作用共同参与。所有化合物中自组装的重复特征是通过弱氢键出现的分子带。这些氢键结合的带在π···π力的作用下进一步堆叠成分子层。弱C–H···O和π···π的协同作用模式是这样的:它们在相互垂直的方向上起作用-氢在分子平面中在其边缘处键合并且π堆积垂直于分子飞机。通过Hirshfeld表面分析对分子间相互作用和晶体堆积进行的研究表明,超过三分之二的紧密接触与弱相互作用有关。Hirshfeld表面和四个香豆素结构的相应指纹图的分解清楚地量化了晶体结构内的相互作用,揭示了每种化合物所经历的相互作用之间的显着相似性。已

  • Synthesis of hydroxycoumarins and hydroxybenzo[f]- or [h]coumarins as lipid peroxidation inhibitors

    Substituted hydroxycoumarins and 7- or 8-hydroxybenzo[f]coumarins were prepared by the treatment of phenols and naphthalenediols, respectively, with malic acid and H2SO4 under microwave irradiation. 7-or 8-Hydroxybenzo[f] coumarins and 6-hydroxybenzo[h] coumarin were synthesized by the reaction of naphthalenediols with ethylpropiolate in the presence of ZnCl2 in refluxing dioxane. The compounds were tested in vitro for their ability: (i) to interact with 1,1-diphenyl-2-picryl-hydrazyl (DPPH) stable free radical, (ii) to inhibit lipid peroxidation, (iii) to scavenge the superoxide anion, (iv) to inhibit the activity of soybean lipoxygenase and (v) to inhibit in vivo the carrageenin-induced rat paw edema. Most of them are potent superoxide anion scavengers and inhibit in vitro lipid peroxidation. The majority of the compounds did not show high lipoxygenase inhibitory activity. No differences were observed between biological responses of hydroxycoumarins and hydroxybenzocoumarins. Compound 3i was found to present a promising antioxidant profile. (C) 2008 Elsevier Ltd.

The Reimer–Tiemann reaction, Lederer–Manasse reaction, bromination using molecular bromine as well as 2,4,4,6‐tetrabromocyclohex‐2,5‐dien‐1‐one, Elbs reaction, and diazocoupling have been carried under controlled conditions to obtain various derivatives. Further, several reactions of aldehyde derivatives of these coumarins have been carried
