Asymmetrische Synthese Delta 3a,4 -ungesättigter bicyclischer Prolin-Analoga und Festphasensynthese mit vinylischen Sulfoximinen
In the first part enantiomerically pure acyclic and cyclic allylic sulfoximines were transformed to the corresponding alpha-titanated compounds and reacted with N-tert-butylsulfonyl a-imino ethyl ester to give acyclic and monocyclic protected alpha-amino acid esters in yields of 32-97%. In all …

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 …
