The reaction of enamines of 1-oxo-indan-2-carboxylic acid anilides (1) with malononitrile yielded 2-arylcarbamylindenylidene-malononitriles (3), which in alkaline solution underwent cyclization to indenopyridines (4).Enamines of 1-oxo-indan-2-carbothionic acid anilides (2) reacted with malononitrile yielding indenothiopyrans (6), which under influence of alkalis were transformed to indenopyridines (8). - Enamines of β-Ketoacid Anilides, o-Aminonitriles, Indenopyridine, Indenothiopyran
