An easy and general sequenced elimination/reduction process by means of samariumdiiodide, in the presence of D(2)O, provides an efficient method for synthesizing 2,3-dideuterioesters 2. The reaction can be also carried out in the presence of H(2)O instead of D(2)O, yielding the corresponding saturated esters 4. Other deuterated esters have been also obtained. A mechanism to explain this synthesis
