Tetrahydrochrysene and cyclofenil derivatives as fluorescent probes of the estrogen receptor
… of unsymmetrical chrysenes IIIb-e, containing ketone, ester, amide, and nitrile groups, was achieved efficiently under mild conditions, by the palladium-mediated arylcarbonylation of intermediate 15 as the key step. However, the RBA of compounds IIIb-e (RBA = 15-40%) is still sufficient for …

Isolation and Partial Characterization of the Toxic Substance from EREMOCARPUS SETIGERUS BENTH
… group tests also indicate the presence of ketone, ester, enol and isolated double bond groups. We believe that the enol form is attributed to the conjugation of the ketone and the ester groups at a β-carbon position.</p> <p>Furthermore, the toxic substance gave a positive terpene-terpenoid …

Electrophilic Affinity Labels and Fluorescent Conjugates for the Estrogen Receptor (Norhexestrol, Aziridine, Hexestrol, Fluorescein, Alkylator)
… of hexestrol by various functionalities: ketone, ester, thioether, or methylene chain. The apparent competitive binding affinity of these derivatives for the estrogen receptor ranges from 1.8-25% of that of estradiol. Most of the norhexestrol aziridine derivatives bind to the receptor in a …

Novel Conjugate Additions and Cyclizations on Multiyne Systems
… Further studies with numerous propargylic and ketone substituents suggested that both steric and electronic factors have a strong impact on 4-pyrone synthesis. Chapter 2 describes a novel hydrogen-bonding directed sequential 1,6/1,4-addition reaction with electron-deficient 1,3-diynes that are …

Iridium-catalyzed borylation of aromatic and aliphatic C-H bonds: methodology and mechanism
… cyanation of the resulting arylboronate esters is described in Chapter 2. This process relies on a previously unknown method to conduct the cyanation of arylboronic esters, and conditions for this new transformation are reported. Conditions for the copper-mediated cyanation of arylboronic …

Ketone Supplementation, Cardiometabolic Health, and Cognition in Humans
… health. Supplementation with exogenous ketone esters (KE) has been shown to increase plasma β-hydroxybutyrate (BHB) and mimic the metabolic effects of LCHF ketogenic diets. Evidence suggests elevated concentrations of plasma BHB may lower blood pressure, improve vascular function, …
