The present invention relates to a novel method for the biocatalytic production of unsaturated dicarboxylic acids by cultivating a recombinant microorganism co-expressing a glutaconate CoA-transferase and a 2-hydroxyglutaryl-CoA dehydratase system. The present invention also relates to corresponding recombinant hosts, recombinant vectors, expression cassettes and nucleic acids suitable for preparing such hosts as well as a method of preparing polyamide or polyester copolymers making use of said dicarboxylic acids as obtained by said biocatalytic production method.

The stereoselectivities of electrophilic additions to acyclicallylicalcohols with and without internalnucleophiles have been assessed with use of previously developed chemical reactivity modeling techniques. Reactions normally assumed to proceed via onium-type intermediates have been investigated. The diastereofacial selectivity of attack by I/sub 2/, Br/sub 2/, PhSeCl, Hg(OAc)/sub 2/, and related
