In this thesis, studies towards the synthesis of the C1-C23-fragment of pulvomycin were performed. The convergent synthesis involves a Julia-Kocienski olefination together with a Horner-Wadsworth-Emmons reaction for the formation of the triene unit and a Nozaki-Hiyama-Kishi coupling as well as a Horner-Wadsworth-Emmons reaction for the formation of the trienone unit. Starting from D-phenylalanine, the scaffold of pulvomycin was obtained in 6% overall yield along 16 steps in the longest linear sequence. Additionally, test reactions for the Yamaguchi esterification and for the removal of the MEM-protecting group were performed using model substrates.
