suitable thioesters represents a mild method for the formation of carbon-carbon bonds and the formation of 1,3-dicarbonyl compounds. A study of the scope and limitations of this reaction for the synthesis of these or mixed 1,3-carbonyl/thiocarbonyl compounds by a base promoted sulfur abstraction rearrangement is described. These reactions were typically very clean and the products were obtained in good
从合适的硫酯中提取硫代表了形成碳-碳键和形成1,3-二羰基化合物的温和方法。描述了对该反应的范围和限制的研究,该反应通过碱促进的硫抽象重排而合成这些或混合的1,3-羰基/硫代羰基化合物。这些反应通常非常干净,仅用30分钟即可获得高收率(65–95%)的产品。该方法对于引入含硫羰基的基团特别有效。因此,它构成了产生新的碳-碳键和混合β-二羰基化合物的区域选择性制备的合成策略。
