A novel, facile and efficient strategy for the one-pot synthesis of β-ketosulfones from readily available sulfonyl chloride, hydrazine hydrate and vinyl azides is described. The reaction proceeded very smoothly affording diverse β-ketosulfones in moderate to good yields. This new procedure has the advantages of environmental benign, easy and simple operation, low cost and wide tolerance of functional
描述了一种从容易获得的磺酰氯,水合肼和乙烯基叠氮化物一锅合成β-酮砜的新颖,简便,有效的策略。反应进行得非常顺利,以中等至良好的收率得到了多种β-酮砜。该新方法具有环境友好,操作简便,成本低廉和对官能团的耐受性强的优点,为获得β-酮砜提供了一个非常引人入胜的方案。
