  The catalytic asymmetric Michael addition of sulfones to nitroalkenes represents a straight-forward approach toward chiral nitroalkenes or cyclic nitrones bearing sulfone functionality in organic synthesis,which are extremely versatile building blocks for the construction of numerous natural products and pharmaceuticals as well.As a consequence of this,many different catalytic enantioselective versions of this fundamental transformation have been reported.
