  • Isolation and synthesis of analgesic and anti-inflammatory compounds from Ochna squarrosa L.

    Two new furanoflavonoids (1, 2), one new chalcone dimer (3) along with six known compounds, chrysophanol, 5-O-methyl squarrosin, 5-methoxy furano[4",5",6,7]flavone, calodenone, lophirone A and lophirone H were isolated from the ethyl acetate-soluble fraction of methanol extract of root bark of Ochna squarrosa. Chrysophanol, calodenone, lophirone A and lophirone H were isolated from this plant for the first time. The structures of all the isolated compounds were confirmed by 1D and 2D spectroscopic data. These compounds were tested for analgesic and anti-inflammatory activity. All the new compounds showed good analgesic and anti-inflammatory activity. A simple and facile method for the cleavage of benzyl ethers using I-2 in trigol is also reported. (c) 2006 Elsevier Ltd. All rights reserved.
  • Diastereoselective Bromocyclization of <i>O</i>-Allyl-<i>N</i>-tosyl-hydroxylamines
    作者:Boris Egart、Dieter Lentz、Constantin Czekelius
    DOI:10.1021/jo3026725
    日期:2013.3.15
    The intramolecular bromoamination of O-allyl-N-tosyl-hydroxylamines results in the formation of isoxazolidines via selective 5-endo-tet cyclization. This process occurs trans-selectively in high yield and diastereoselectivity. The obtained bromo-isoxazolidines provide access to other useful building blocks, such as 2-azido-aminoalcohols, diaminoalcohols, and aziridines.
  • Chemical Synthesis of Hydroxycinnamic Acid Glucosides and Evaluation of Their Ability To Stabilize Natural Colors via Anthocyanin Copigmentation
    作者:Stephanie Galland、Nathalie Mora、Maryline Abert-Vian、Njara Rakotomanomana、Olivier Dangles
    DOI:10.1021/jf071205v
    日期:2007.9.1
    This work describes the chemical synthesis of O-aryi-beta-D-glucosides and 1 -O-beta-D-glucosyl esters of hydroxycinnamic acids. In particular, OLaryl-beta-D-glucosides were efficiently prepared via a simple diastereoselective glycosylation procedure using phase transfer conditions. Despite the lability of its ester linkage, 1-O-beta-D-caffeoylglucose could also be obtained using a Lewis acid catalyzed glycosylation step and a set of protective groups that can be removed under neutral conditions. Hydroxycinnamic acid O-aryl-beta-D-glucosides were then quantitatively investigated for their affinity for the naturally occurring anthocyanin malvin (pigment). Formation of the pi-stacking molecular complexes (copigmentation) was characterized in terms of binding constants and enthalpy and entropy changes. The glucosyl moiety did not significantly alter these thermodynamic parameters, in line with a binding process solely involving the polyphenolic nuclei.
