Epimerization, transacylation and bromination of dihydroquercetin acetates; synthesis of 8-bromodihydroquercetin

Autor: Eberhard Kiehlmann, Monica G. Szczepina

Publikováno v: Open Chemistry, Vol 9, Iss 3, Pp 492-498 (2011)

Dihydroquercetin (dhq) and its 3-acetate react with acetic anhydride in the absence of a base catalyst to yield mixtures of partially acetylated products. Three new esters were characterized by NMR spectroscopy as dhq 3,7,3′-triacetate, 3,7,4′-tr

Crystal structures of dihydroquercetin 3-acetate and dihydroquercetin 3,3'4',7-tetraacetate: hydrogen bonding in 5-hydroxyflavanones

Autor: Michael J. Zaworotko, Konstantin V. Domasevitch, Kumar Biradha, Eberhard Kiehlmann

Publikováno v: Canadian Journal of Chemistry. 77:1436-1443

The molecular structures of dihydroquercetin 3-acetate 3 and dihydroquercetin 3,3',4',7-tetraacetate 4 were determined by single crystal X-ray analysis. Comparison of their crystal data with those of 16 known 5-hydroxyflavanones shows intramolecular

Factors that affect the degradation of naphthenic acids in oil sands wastewater by indigenous microbial communities

Autor: Margo M. Moore, Linda J. Pinto, Leah I. Bendell-Young, Eberhard Kiehlmann, June W. S. Lai

Publikováno v: Environmental Toxicology and Chemistry. 15:1482-1491

The acute toxicity of wastewater generated during the extraction of bitumen from oil sands is believed to be due to naphthenic acids (NAs). To determine the factors that affect the rate of degradation of representative NAs in microcosms containing wa

The biotransformation of chrysene to trans-1,2-dihydroxy-1,2-dihydrochrysene by filamentous fungi

Autor: Eberhard Kiehlmann, Linda J. Pinto, Margo M. Moore

Publikováno v: Canadian Journal of Microbiology. 42:604-608

The purpose of this study was to assess the ability of filamentous fungi isolated from petroleum-contaminated soils to oxidize chrysene. Only 4 of the 17 isolates known to oxidize pyrene and benzo[a]pyrene were found to produce polar products when in

The oxidation of pyrene and benzo[a]pyrene by nonbasidiomycete soil fungi

Autor: Eberhard Kiehlmann, L. A. Launen, Christine Wiebe, Linda J. Pinto, Margo M. Moore

Publikováno v: Canadian Journal of Microbiology. 41:477-488

The purpose of this study was to determine the ability of nonbasidiomycete soil fungi to oxidize pyrene (four rings) and benzo[a]pyrene (BaP) (five rings). Fungi were isolated from five different soils in which the polycyclic aromatic hydrocarbon con
