    • Simple cyanoacetates or other unsubstituted activated methylenic compounds add to β-substituted vinyl selenones generating directly 2-substituted cyclopropanecarboxylic esters through an alternative cascade process which involves a Michael addition, a proton exchange and a cyclization by displacement of the PhSeO2 group.[6j,l,m] The organocatalytic version of this process merits investigations. These are currently under way in our laboratory
