An Improved synthetic procedure is described for the preparation of 2,3-dialkylated 2,3-dihydrothiin-4-ones using organocopper chemistry. The utility of these, and the corresponding saturated compounds for the synthesis of Δ3- and Δ2-2,3-disubstituted cyclopentenones via the Ramberg-Bäcklundreaction is discussed. The application of this methodology to a formal total synthesis of the antimicrobial
