Neue Ankergruppen für die enantioselektive kombinatorische Festphasensynthese
Within the scope of this work three new linkers for solid phase synthesis have been developed. Starting with functionalized amines these were diazotated and coupled onto a resin with secondary amine functionalities. This triazene-linker (T1-linker) allows the traceless cleavage of arenes. On the …

Totalsynthese von (+)-2-epi-Deoxoprosopinin und neue Hydrazin-Harze für die organische Festphasensynthese
This Ph. D. thesis deals with two different topics of organic synthesis, the total synthesis of (+)-2-epi-deoxoprosopinine and the development and application of novel haydrazine resins for solid phase synthesis. In the first part, the asymmetric synthesis of (+)-2-epi-deoxoprosopinine in twelve …

Asymmetrische Synthese von bicyclischen Alpha-Aminosäuren durch intramolekulare Pauson-Khand-Reaktion von l-Alkenylsulfoximinen und Festphasensynthese mit Allylsulfoximinen
Described is an asymmetric synthesis of novel bicyclic alpha-amino acids having a hexahydro cyclopenta[c]pyridine skeleton, carrying an enone structural element, and a substituent in beta-position. Starting from enantiomerically pure (S)-N,S-Dimethyl-S-phenylsulfoximine allylic sulfoximines could …
