Abstract

GRAPHICSThe first enantioselective ruthenium olefin metathesis catalysts have beenprepared, and high enantiomeric excesses (up to 90%) are observed in the desymmetrization of achiral trienes. A model consistent with the stereochemical outcome of the reactions is described and suggests side-on olefin binding and reorganization of the halide ligands.
