From Nef‐Isocyanide Adducts toward Functionalized 5‐Iminothiazolidines Containing Polarized CC Bonds

An efficient synthesis of alkyl 5-(alkylimino)-3-aryl(alkyl)-2-(dicyanomethylene)-4-hydroxythiazolidine-4-carboxylates, containing polarized CC bonds, via reaction of malononitrile, arylisothiocyanates, and the Nef-isocyanide adducts, under basic conditions, is described.
