Developing Reactions of Strained Rings : Enantioselective Desymmetrization of meso-Diaminocyclopropanes and Annulation of Donor-Acceptor Aminocyclobutanes

Daniele Perrotta

Carbo- and heterocyclic structures containing nitrogen-substituted stereocenters are recurrent structural motifs in natural and bioactive compounds, therefore constituting a privileged class of synthetic targets. In this regard, substituted three- and four ...

"Palladium-Catalyzed Diamination of Alkynes in Synthesis of Tetracycles" and "Copper-Catalyzed Cyanoalkylation of Unactivated Alkenes"

Minh Tu Ha

The thesis deals with the development of transition metal-catalyzed difunctionalization of alkenes and alkynes, which can be categorized into two major topics: (1) palladium-catalyzed diamination of alkynes for the synthesis of tetracycles; (2) copper-cata ...

Synthesis of Adamantane Aminoethers with Antitubercular Potential

Stewart Cole, Anthony Vocat

Background: Intrigued by the fact that aminoadamantane derivatives, bearing the active 1,2-ethylenediamine moiety, are promising antitubercular agents, we report herein the synthesis and the antitubercular evaluation of N,N'-substituded-4,4'-[adamantane-2, ...

Cyclic Hypervalent Iodine Reagents for Atom-Transfer Reactions: Beyond Trifluoromethylation

Jérôme Waser, Durga Prasada Rao Hari, Yifan Li, Maria Victoria Vita

Hypervalent iodine compounds are privileged reagents in organic synthesis because of their exceptional reactivity. Among these compounds, cyclic derivatives stand apart because of their enhanced stability. They have been widely used as oxidants, but their ...

Synthesis and structure-activity relationship of 2,6-disubstituted pyridine derivatives as inhibitors of beta-amyloid-42 aggregation

Andrea Pfeifer, Andreas Muhs, Paolo Paganetti

It is assumed that amyloid-beta aggregation is a crucial event in the pathogenesis of Alzheimer's disease. Novel 2,6-disubstituted pyridine derivatives were designed to interact with the beta-sheet conformation of A beta via donor-acceptor-donor hydrogen b ...

Nanoporous Materials Can Tune the Critical Point of a Pure Substance

Berend Smit, Efrem Daniel Braun, Sondre Kvalvag Schnell

Molecular simulations and NMR relaxometry experiments demonstrate that pure benzene or xylene confined in isoreticular metal-organic frameworks (IRMOFs) exhibit true vapor-liquid phase equilibria where the effective critical point may be reduced by tuning ...

Reaction of bromine and chlorine with phenolic compounds and natural organic matter extracts - Electrophilic aromatic substitution and oxidation

Urs von Gunten, Eva Maria Rodriguez Franco

Phenolic compounds are known structural moieties of natural organic matter (NOM), and their reactivity is a key parameter for understanding the reactivity of NOM and the disinfection by-product formation during oxidative water treatment. In this study, spe ...

Exploiting Dispersion-driven Aggregators as a Route to New One-dimensional Organic Nanowires

Anne-Clémence Corminboeuf, Riccardo Petraglia, Adrien Georges Nicolai, Hongguang Liu

The efficiency of charge carrier mobility in organic semiconductors is heavily dependent upon the long-range organization (i.e., morphology) and the local relative arrangement of the transporting molecules. Here, we exploit London dispersion forces as a de ...

Aromatic Homologation by Non- Chelate- Assisted RhIII- Catalyzed C -H Functionalization of Arenes with Alkynes

Nicolai Cramer, Van Manh Pham

Larger condensed arenes are of interest owing to their electro- and photochemical properties. An efficient synthesis is the catalyzed aromatic annulation of a smaller arene with two alkyne molecules. Besides difunctionalized starting materials, directed CH ...

Molecular Engineering of Push-Pull Porphyrin Dyes for Highly Efficient Dye-Sensitized Solar Cells: The Role of Benzene Spacers

Michael Graetzel, Shaik Mohammed Zakeeruddin, Aswani Yella, Chi-Lun Mai

Porphyrins have drawn much attention as sensitizers owing to the large absorption coefficients of their Soret and Q bands in the visible region. In a donor and acceptor zinc porphyrin we applied a new strategy of introducing 2,1,3-benzothiadiazole (BTD) as ...
