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
