(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).
(E)-2-甲醛基-3-(2-呋喃基)丙烯腈(I)与一次芳香胺反应,生成3-(芳胺基)-2-[5-(芳胺基)-2-氧代-3-环戊烯-1-基]丙烯腈(IVa-IVi)。在吡啶中,将I与氮碱盐缩合得到2-(R-氨基甲亚甲基)-3-(2-呋喃基)丙烯腈(Va-Vm)。
