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-Bäcklund reaction is discussed. The application of this methodology to a formal total synthesis of the antimicrobial
描述了使用有机铜化学方法制备2,3-二烷基化的2,3-二氢噻吩-4-酮的改进的合成方法。这些实用程序以及用于Δ合成的相应的饱和化合物3 -和Δ 2经由兰堡-巴克伦反应-2,3-二取代的环戊烯酮进行了讨论。描述了该方法在抗菌天然产物四氢二烯酮B的正式全合成中的应用。
