The Ramberg–Bäcklundreaction has been employed to prepare protected 2,3-disubstituted cyclopent-3-enones which have been converted into cyclopent-3- and -2-enones; the α-iodosulphone precursors were obtained by a double Michael approach using a three-component coupling sequence to introduce the alkyl substituents and this methodology has been used to develop a shortsyntheticroute to the antimicrobial

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
