Studies on the Zinc-mediated Phenyl and Alkynyl addition to Carbon-heteroatom double bonds
This thesis describes the work carried out by the author in the field of enantioselective dialkylzinc-mediated carbon-carbon bond forming reactions. In particular, the asymmetric addition of C(sp2) and C(sp) nucleophiles to carbon-heteroatom double bonds was the subject of this research. In the …

Asymmetrischer katalytischer Phenyltransfer zur Synthese von Diarylmethanolen und Diarylmethylaminen
Enantiopure diarylmethanols and diarylmethylamines are important intermediates in the synthesis of biologically active compounds, since their derivatives have e. g. antihistaminic properties. For example, the (S)-enantiomer of the commercially important non-sedating antihistamine agent Cetirizine …

Katalytische, enantioselektive Synthesen von Diarylmethanolen und Allylalkoholen
In this research new, catalytic, enantioselective aryl transfer reactions to aldehydes for the synthesis of chiral diarylmethanols were developed. Diarylmethanols are important intermediates for the synthesis of pharmaceutically active compounds. In the foregoing research, it was found that, in …

Synthese neuartiger Sulfoximine für die asymmetrische Metallkatalyse
In this work various beta-hydroxysulfoximines was synthesized. We proved their catalytic applicability in asymmetric phenyl transfer reactions onto aldehydes. Enantiomerically enriched diarylmethanols have been prepared by catalyzed asymmetric phenyl transfer reactions onto aromatic aldehydes with …
