addition reaction of sulfonamides. However, most of these reagents are useful for the synthesis of N-alkylsulfonamides but not of N,N-dialkylated adducts.2–5 Therefore, it seems highly desirable to develop an efficient reagent for the preparation of N,N-dialkylsulfonamides. Solvent-free organic reactions have become as a useful protocol in organic synthesis.7,8 The utilization of microwave irradiation
磺酰胺的 N,N-二烷基衍生物因其作为抗溃疡剂、抗抑郁剂、止吐镇痛剂、精神兴奋剂和抗炎剂的潜在应用而具有重要意义。 1 磺酰胺与亲电子双键的 Aza 共轭加成是一种有用的合成N,N-二烷基磺酰胺的路线。事实上,据我们所知,文献中几乎没有研究过这种转变。已应用Al2O3、ZnO、3 MgO、4 K2CO3和PBu3等试剂实现磺胺类的氮杂共轭加成反应。然而,这些试剂中的大多数可用于合成 N-烷基磺酰胺,但不适用于 N,N-二烷基化加合物。2-5 因此,开发一种用于制备 N,N-二烷基磺酰胺的有效试剂似乎是非常可取的。
