Abstract
β-elimination of α-halo-β-hydroxyesters 1 was achieved by using samarium diiodide as a metalating reagent, and afforded di- and trisubstituted (E)-α,βunsaturated esters 2 with total steroselectivity. This method has also been extended to the corresponding disubstituted (E)-α,β-unsaturated amides.
