Sodium dithionite as a bifunctional reagent for the cyanoalkylsulfonylation of Morita-Baylis-Hillman acetates with cycloketone oxime esters.

For the first time, an inexpensive and readily available inorganic salt, sodium dithionite (Na2S2O4), has been demonstrated for the single electron reduction of cycloketone oxime esters. The resultant cyanoalkyl radicals are efficiently transformed i…
