The synthesis of highly functionalized fluorinated piperidines is described. The key step in this synthesis is a ring-closing metathesis reaction involving fluoride-substituted olefins, which leads to the corresponding cyclic vinyl fluorides. Several sequences to arrive at differently substituted piperidines have been evaluated. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
