Aqueous Oxidation of Sulfonamide Antibiotics: Aromatic Nucleophilic Substitution of an Aniline Radical Cation

Jeremy Samuel Arey, Peter Rudolf Tentscher

Sulfonamide antibiotics are an important class of organic micropollutants in the aquatic environment. For several, sulfur dioxide extrusion products have been previously reported upon photochemical or dark oxidation. Using quantum chemical modeling calcula ...

Conjugation of organoruthenium(II) 3-(1H-benzimidzol-2-yl)-pyrazolo[3,4-b]pyridines and indolo-[3,2-d]benzazepines to recombinant human serum albumin: a strategy to enhance cytotoxicity in cancer cells

Paul Joseph Dyson, Angela Casini, Fabio Edafe

Following our strategy of coupling cyclin-dependent kinase (Cdk) inhibitors with organometallic moieties to improve their physicochemical properties and bioavailability, five organoruthenium complexes (1c-5c) of the general formula [RuCl(eta(6)-arene)(L)]C ...

Understanding Chloroquine Action at the Molecular Level in Antimalarial Therapy: X-ray Absorption Studies in Dimethyl Sulfoxide Solution

Andrzej Sienkiewicz

X-ray absorption spectroscopy is used to determine the local atomic structure around the iron atom from a soluble synthetic analogue of malaria pigment (hemozoin), cf. ferrimesoporphyrin IX of mesohematin anhydride, in the absence or presence of chloroquin ...

BCl3-Mediated Ene Reaction of Sulfur Dioxide and Unfunctionalized Alkenes

Pierre Vogel, Dean Markovic, Chandra Mouleeswara Rao Volla

The first ene reactions of SO2 and unfunctionalized alkenes are reported. Calculations suggest that the endergonic ene reactions of SO2 with alkenes can be used to generate beta,gamma-unsaturated sulfinyl and sulfonyl compounds. Indeed, in the presence of ...

New developments in iron-catalyzed carbon-carbon bond forming reactions

Chandra Mouleeswara Rao Volla

The goal of this thesis is to develop new carbon-carbon bond forming reactions using inexpensive and simple coupling partners like aryl halides (pseudohalides), sulfonyl derivatives, Grignard reagents, alkenes and alkynes with metal catalysis, preferably u ...

Ligandless Iron-Catalyzed Desulfinylative C-C Allylation Reactions using Grignard Reagents and Alk-2-enesulfonyl Chlorides

Pierre Vogel, Dean Markovic, Chandra Mouleeswara Rao Volla

Alk-2-enesulfonyl chlorides 1-4 were synthesized by the BCl3-promoted ene reaction of alkenes with SO2. These sulfonyl chlorides were then used as electrophilic partners in iron-catalyzed desulfinylative cross-coupling reactions with different Grignard rea ...

Electrodeposition and Characterization of Bismuth Telluride Nanowires

Simon Granville

In this work, we report thermoelectric measurements on electroplated bismuth telluride nanowires. Porous polycarbonate membranes, obtained by ion-track irradiation lithography, were chosen as electroplating templates. Bismuth telluride nanowires were achie ...

Use of sultines in the asymmetric synthesis of polypropionate antibiotics

Pierre Vogel, Maris Turks, Cotinica Craita, Freddy Fonquerne, Laure Bouchez, Christopher Flowers, Xiaogen Huang

At low temperature and in the presence of an acid catalyst, SO2 adds to 1,3-dienes equilibrating with the corresponding 3,6-dihydro-1,2-oxathiin-2-oxides (sultines). These compounds are unstable above -60 degrees C and equilibrate with the more stable 2,5- ...

Palladium-Catalyzed Desulfitative Mizoroki-Heck Coupling Reactions of Sulfonyl Chlorides with Olefins in a Nitrile-functionalized Ionic Liquid

Paul Joseph Dyson, Pierre Vogel, Zhaofu Fei, Dongbin Zhao, Chandra Mouleeswara Rao Volla

Aryl and alkenyl sulfonyl chlorides can be used in Heck-Mizoroki-type couplings with mono- and disubstituted olefins in a nitrile-functionalized ionic liquid, viz. [C3CNpy][Tf2N]. Advantages over previously reported methods include: (1) use of a cheap cat ...

Transition metal-catalyzed carbon-carbon cross-coupling reactions using sulfonyl derivatives

The goal of this thesis was to find conditions to form C-C double bond and single bond using sulfonyl derivativies, which are arising from the Vogel's oxyallylation cascades. In a second chapter, it is shown that 2-methylprop-2-ene-1-sulfonyl fluorides can ...
