Remarkably mild and efficient catalytic Sakurai reaction of N-alkoxycarbonylamino sulfones with allyltrimethylsilane using indium(III) chloride

The Sakurai reaction of N-alkoxycarbonylamino sulfones with allyltrimethylsilane in the presence of a catalytic amount of indium(III) chloride at room temperature produces the corresponding protected homoallylic amines in high yields.
