Synthese chiraler Sulfone aus Sulfoximinen in Lösung und an fester Phase
Synthesis of chiral sulfones using sulfoximines in solution and on solid phase Abstract: Allylic sulfoximines were synthesised in a one pot reaction starting from (S)-N,S-dimethylphenylsulfoximine in high yields. The following g-hydroxyalkylation with functionalised aldehydes was achieved with …

Asymmetrische Synthese und stereoselektive Substitution allylischer Sulfoximin-funktionalisierter Homoallylalkohole
Enantiopure acyclic (E)- and (Z)-configured allylic sulfoximines have been synthesized from N,S-dimethyl-S-phenylsulfoximine and aldehydes via the addition-elimination-isomerization route. Titanation of lithiated (E)- and (Z)-configured allylic sulfoximines with Chlortrisdiethylanimotitan and …

Asymmetrische C-C-Knüpfungsreaktionen mit lithiierten Alkyl- und Allylsulfoximinen
Asymmetric C–C–bonding reactions with lithiated alkyl and allyl sulfoximines This thesis deals with the use of (S)-N,S-dimethylphenylsulfoximine in asymmetric synthesis. The lithiated (S)-N,S-dimethylphenylsulfoximine can react with alpha-, beta-unsaturated carbon acid esters. This Michael-type …

Asymmetrische Synthese funktionalisierter Homoallyl- und Homopropargylalkohole mittels der Sulfoximin-Route
This dissertation describes new methods of asymmetric synthesis of diastereomeric and enantiomeric pure allylic alcohols. Via the sulfoximine-route by Gais et al. new chiral homoallyllic alcohols were synthesized. Elimination of the sulfoximine-group lead to optically pure homopropargylic alcohols. …

Chirale Tris(amido)titanaallylsulfoximine: Stereoselektive Hydroxyalkylierung, Struktur und Dynamik
This thesis deals with stereoselective hydroxyalkylation reactions of E- and Z-configured allylic sulfoximines. Titanation of lithiated allylic sulfoximines with chlorotrisdiethylaminotitan and subsequent reaction of the resulting mono(2-alkenyl)tris(diethylamido)titan(IV)-complexes with aldehydes …

Synthese neuer C 1-symmetrischer Monosulfoximine und deren Anwendung als Liganden in der asymmetrischen Katalyse
This PhD thesis describes the development of a new class of C1-symmetric monosulfoximines and their application as ligands in asymmetric catalysis. The main question, with which the research was concerned, is whether a ligand which does not possess C2-symmetry and has only one chiral sulfoximine …

Asymmetrische Synthese 3-substituierter 4-Methylenproline und Untersuchungen zur Metathese mit vinylischen Sulfoximinen
In the first part an enantio- and diastereselective synthesis of 3-substituted 4-methylene prolines was developed. (S)-N,S-dimethyl-S-phenylsulfoximine was tansformed via an addition, elimination, isomerization route (AEI-route) into the corresponding mixture of E and Z allylic sulfoximines. This …
