The first part of this thesis investigates a short route to (–)-Vinigrol
via an intramolecular
Diels-Alder-reaction between an 2-oxyfurane and an electron-deficient alkene or alkyne. The required fragments were synthesised and connected through a sp
3-sp
3-coupling reaction. Despite intensive efforts, no
Diels-Alder-Produkt was identified under thermal,
Lewis-acidic or high-pressure conditions. The second part deals with a search for new fluoroquinolone-antibiotics. Therefore, a hydrogen bond-mediated combinatorial library with 35 fragments was built up. With the use of an agarosegel-assay no enzyme inhibition was observed in the 147 combinations tested.
