range of branched sp3‐functionalised sulfonamides, a compound class for which few reported methods exist. By reacting benzyl sulfonamides with allylic acetates in the presence of Pd0 catalysts and base at room temperature, direct allylation was efficiently performed, yielding products that are analogues of structural motifs seen in biologically active small molecules. The reaction was performed under
据报道,Pd催化的烯丙基化的新应用使得能够合成一系列支链的sp 3官能化的磺酰胺,这是报道的方法很少的化合物类别。在室温下,在Pd 0催化剂和碱的存在下,通过使苄基磺酰胺与烯丙基乙酸酯反应,可以有效地进行直接烯丙基化,生成的产物与具有生物活性的小分子中的结构图案类似。该反应在温和的条件下进行,可应用于纳摩尔的sigma-受体粘合剂,因此可实现后期功能化并有效扩展类药物的化学空间。
