A novel imide-forming reaction is described in which 3-(dicyanomethylidene) phthalide (pseudoanhydride) reacts with amines at room temperature. The pseudoanhydride was synthesized by condensation of phthalic anhydride with malononitrile followed by treatment with phosphrous oxychloride.
Reactions of Heterocyclic Ketene Aminals with 2-[3-Oxoisobenzofuran-1(3H)-ylidene]malononitrile: Synthesis of Novel Polyfunctionalized 1,4-Dihydropyridine-Fused 1,3-Diazaheterocycles
An efficient method has been developed for the synthesis of a novel kind of polyfunctionalized 1,4-dihydropyridine-fused 1,3-diazaheterocycles via the reactions of heterocyclic ketene aminals (HKAs) with 2-[3-oxoisobenzofuran-1(3H)-ylidene]malononitrile.

Spiro heterocycles frequently occur in bioactive molecules. In the pursuit of neonicotinoids with Spiro heterocycles, three types of novel neonicotinoids with spirobenzofuranone, spirooxindole or spiroacenaphythylenone framework were designed and synthesized. Insecticidal evaluation showed that some of spirobenzofuranone containing neonicotinoids exhibited moderate activity against cowpea aphid, armyworm or brown planthopper.
