Simple Preparation of 4,5-Disubstituted 2-Cyclopentenones

( 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)propenenitril...
