Starting from a propargylic fluoride, a three step sequence led to syn and anti 9-fluoro analogues of the disparlure pheromone. During these studies an unusual C-C bond cleavage of an epoxide has also been discovered. (C) 2001 Elsevier Science B.V. All rights reserved.
Carbon-13 and fluorine-19 NMR experiments in a chiral polypeptide liquid crystalline solvent (PBLG) are used to establish enantioselective propargylic monofluorination.

The cycloadditions of nitrileoxides with new and previously studied allylic fluorides were examined. The 1,3-dipolar cycloaddition reactions were also investigated theoretically with density functional theory (B3LYP) based transition-state modelling. The predictions provided reasonable agreement with experiment, indicating that both steric and electronic effects have important influences on the stereoselectivities

New enones with mono-, gem-difluoro- or trifluoro chains are easily obtained through the Meyer–SchusterRearrangement (MSR), using phosphomolybdic acid as the catalyst selected after extensive screening.

Propargylic fluorides are converted in a short sequence involving hydrostannylation, iodination and Pd catalysis into new stereodefined polyunsaturated systems with a fluorine atom in the allylic position. (C) 1999 Published by Elsevier Science Ltd. All rights reserved.
