We describe the development of a computational approach for the identification of every possible biochem. reaction from a given set of enzyme reaction rules that allows the de novo synthesis of metabolic pathways composed of these reactions, and the evalua ...
Conversion of unactivated olefins to azides was achieved with high Markovnikov selectivity for a broad range of alkenes by using 6 mol % Co(BF4).6H2O and ligand I, with 3 equiv of tosyl azide as the nitrogen source and simple silanes (e.g., PhSiH3, tetrame ...
The goal of this thesis was to open a new route to the synthesis of conjugated trienes using a new SO2-based C-C bond forming reactions developed in Lausanne. In addition, the potential of SO2 for applications in synthetic organic chemistry has been exploi ...
In the presence of sulfur dioxide and an acid promoter, (-)-(1E,3Z)-2-methyl-1-((1S)-1-phenyleth- oxy)penta-1,3-dien-3-yl isobutyrate reacts with (Z)-3-(trimethylsilyloxy)-pent-2-ene giving a silyl sulfinate intermediate that undergoes, in the presence of ...
The heterogeneous photoinduced electron transfer involving dyes adsorbed at the interface between two immiscible electrolyte solutions and redox molecules located in the adjacent phase manifests itself as photocurrent responses under potentiostatic conditi ...
Motivation: Metab., the network of chem. reactions that make life possible, is one of the most complex processes in nature. We describe here the development of a computational approach for the identification of every possible biochem. reaction from a given ...
Sulphur dioxide reacts with 1-oxydienes generating zwitterions which are quenched by enoxysilanes to form substituted silyl alkenylsulfinates. These intermediates are desilylated with Bu4NF and the resulting sulfinates react with MeI giving the correspondi ...
The goal of our project (HES-SO n°11246) is to develop chemometric methods that enhance the development of chemical reactions. Semi-batch experiments are performed using a fully automated chemical reactor. Real-time analytical data, infrared (IR) spectra f ...
The first aza-C-disaccharide (D-azaMan-beta-CHz-(1 -> 6)-D-Man-alpha-OMe) that mimicks alpha-D-Manp-(1 -> 6)-alpha-D-ManOMe was made in 1994 by Johnson and coworkers. Several synthetic approaches to these disaccharide mimetics have been proposed. These are ...
The method and app. for carrying out electrochem. promoted catalytic reactions, i.e., catalytic reactions where the catalytic rate and selectivity is modified by applying an elec. current or potential between the porous catalyst film which is deposited on ...
