Applications of Layer-by-Layer Films in Electrochromic Devices and Bending Actuators
… materials and some new materials (Prodot-Sultone) was performed. Work was done to achieve the optimum thickness and number of bilayers in LbL films resulting in high-contrast and fast switching. Device sizes were varied for comparison of the performance of the lab-made prototype device …

Regioselective Synthesis of Polysaccharide-based Polyelectrolytes
… 6-imidazolo-6-deoxycellulose with propane sultone, leading to a new synthetic pathway to zwitterionic cellulose derivatives. In addition to cationic and zwitterionic derivatives, we found a simple, efficient route to carboxyl-containing polysaccharide derivatives from curdlan esters via …

Synthetic and stereochemical aspects of enantioselective copper catalysed C-H insertion reactions leading to cyclopentanones and sultones
… and up to 95% ee in the synthesis of sultones. Chapter One contains a comprehensive review providing an insight into the effect of substitution on the outcome of transition metal catalysed intramolecular C–H insertion reactions of α-diazocarbonyl compounds. This overview specifically …

Asymmetrische Synthese von Beta-Aminosulfonaten, Beta-Sultamen und Gamma-Sultonen
… sulfonates, beta-sultams and gamma-sultones has been developed. The key step of the synthesis is the Lewis acid (zinkbromide) catalyzed aza-Michael addition of the enantiopure hydrazines (S)-1-amino-2-methoxymethyl-pyrrolidine (SAMP) or …

Asymmetrische Synthese von Sulfonsäurederivaten
… Additionally, the ring-opening reactions of sultones with heteronucleophiles and the Michael-reactions of sulfonic acid esters with various Michael-acceptors were investigated.

Asymmetric synthesis of sultones and sulfonic acid derivatives
… route to alpha, gamma-substituted gamma-sultones via alpha-allylation of lithiated sulfonates bearing 1,2:5,6-di-O-isopropylidene-alpha-D-allofuranose as a chiral auxiliary has been developed. High asymmetric inductions of the alpha-allylations were achieved along with good to excellent …
