(E-2-Formyl-3-(2-furyl)propenenitrile (I) reacts with primary aromatic amines under formation of 3-(arylamino)-2-[5-(arylamino)-2-oxo-3-cyclopenten-1-yl]propenenitriles (IVa-IVi). Condensation of I with salts of nitrogen bases in pyridine affords 2-(R-aminomethylidene)-3-(2-furyl)propenenitriles (Va-Vm).
