One-Pot Aryl-1,4-thiomorpholine 1,1-Dioxide Synthesis via Double 1,4-Addition of in situ Reduced Nitroarenes to Divinyl Sulfones
摘要:
One-pot reduction-triggered double aza-Michael type 1,4-addition reactions of various nitroarenes to divinyl sulfones were investigated. In the presence of indium/AcOH in MeOH or in sat. aq NH(4)Cl/MeOH, nitroarenes and divinyl sulfones were cyclized to give 1,4-thiomorpholine 1,1-dioxides.

was developed for facile access to cyclic and acyclic β-amino sulfones “on-water” using a microwave. A variety of aromatic and aliphatic amines undergo double aza-Michaeladdition on the surface of the water with water-insoluble divinyl sulfones upon microwave irradiation at 150 °C for 10 min to mostly afford solid cyclic β-amino sulfones as easily separable products in excellent yields by simple filtration
