developed for the synthesis of (2-nitro-1-phenylethyl)malononitriles through a Michaeladdition reaction between substituted nitroolefins and masked acyl cyanide reagents, serving as carbon monoxide equivalents. Under mild conditions, the reaction took place with excellent yields (90–98%), providing a short entry into a series of the title compounds in a scalable fashion. An asymmetric version of this
