title: Four-component reaction of N-sulfonylimines, (cyanomethylene)triphenylphosphorane, nitromethane, and formaldehyde for the synthesis of 3-substituted 2-methylene-4-nitrobutanenitriles.
abstract: An efficient four-component synthesis of 3-substituted 2-methylene-4-nitrobutanenitriles has been developed from N-sulfonylimines, (cyanomethylene)triphenylphosphorane, nitromethane, and formaldehyde in the absence of catalysts and additives at room temperature.
