  • Beitrag zur Kenntnis der 2-Aryl-benzopyryliumsalze
    作者:Ch. Michaelidis、R. Wizinger
    DOI:10.1002/hlca.19510340608
    日期:——
    Durch Kondensation von Cumarin und 7-Oxycumarin mit Phenolen, Phenoläthern und tertiären aromatischen Aminen sowie durch Kondensation von α-Oxyaldehyden mit Acetophenonen wird eine Anzahl neuer 2-Aryl-benzopyryliumsalze dargestellt. Es ergibt sich, dass das 2-Phenylbenzopyryliumion ein sehr stark auxochromempfindliches System ist.

  • Anthocyanidins and related compounds—XVII

    Flavylium salts and 2-hydroxychalcones (1-phenyl-3-(2-hydroxyphenyl)-2-propen-1-ones) react with hydroxylamine in pyridine to form 2,5-dihydroisoxazoles. These undergo thermal and acid-catalyzed rearrangements to isomeric 4,5-dihydroisoxazoles and chalcone oximes, respectively. With hydrazine, flavylium salts yield phenolic 4,5-dihydro-3,5-diphenyl-1H-pyrazoles. Since these readily condense with acetone
    黄酮盐和2-羟基查耳酮(1-苯基-3-(2-羟基苯基)-2-丙烯-1-酮)与吡啶中的羟胺反应形成2,5-二氢异恶唑。它们分别进行热和酸催化重排,分别形成异构体4,5-二氢异恶唑和查尔酮肟。黄酮盐与肼一起产生酚类4,5-二氢-3,5-二苯基-1H-吡唑。由于这些很容易与丙酮缩合形成环丙酮化物,因此酰化反应涉及在黄酮核的2位发生最初的亲核攻击。
  • Antiradical and reductant activities of anthocyanidins and anthocyanins, structure–activity relationship and synthesis
    作者:Hussein M. Ali、Wafaa Almagribi、Mona N. Al-Rashidi

    Eight anthocyanidins, seven anthocyanins and two synthesized 4'-hydroxy flavyliums were examined as hydrogen donors to DPPH, ABTS and hydroxyl radicals, and as electron donors in the FRAP assay. Most compounds gave better activities than trolox and catechol. A structure-activity relationship (SAR) study showed that, in the absence of the 3-OH group, radicals of the 4, 5 or 7-OH groups can only be stabilized by resonance through pyrylium oxygen, while 3-OH group improved hydrogen atom donation because of the stabilization by anthocyanidin semiquinone-like resonance. Electron donation was also enhanced by the 3-OH group. Both anthocyanidins and their respective anthocyanins showed similar trends and close activities. Different types of sugar unit bonded to the 3-OH group or counter ion had minor effect on activities. The catechol structure improved both hydrogen and electron donation. Compounds lacking the catechol structure had a decreasing order of H-atom and electron donation (Mv > Pn > Pg > Ap > 4'-OH-flavylium) consistent with the decreasing number of their hydroxyl and/or methoxy groups.
