SYNTHESIS OF (+/-)-DIMETHYL CURVULARIN BASED ON THE PALLADIUM-CATALYZED CARBONYLATION OF 3,5-DIMETHOXYBENZYL CHLORIDE USING A BUTADIENE TELOMER AS A BUILDING BLOCK

Palladium -catalyzed carbonylation of 3,5-dimethoxybenzyl chloride (13) with benzyl 7-hydroxyoctanoate (12) afforded benzyl 7-(3,5-dimethoxyphenylacetoxy)octanoate (6) in 70percent yield, which is the precursor of Curvularin (4).The ester (12) was easily prepared from the butadiene telomer obtained by the palladium-catalyzed reaction of butadiene with acetic acid.

Halogenated olefins, processes for their preparation and their use as pesticides

This are described new halogenated olefines of general formula I STR1 in which X1, X2, X3, n and A have the meanings given in the description as well as processes for their preparation. The compounds can be used as pesticides especially against insects and acarids.
