    Description / Table of Contents: Zusammenfassung Einige neue Benzopyran- und Benzopyranopyridin-derivate wurden durch Kondensation von 2-Amino-1,1,3-tricyanopropen (1) und 2-Amino-1-cyanopropen-1,3-dicarbonsäuredimethylester (2) mit Salicylaldehyd und Behandlung der Reaktionsprodukte mit aktiven Methylenreagenzien dargestellt. Die spektroskopischen Daten der neuen Verbindungen werden diskutiert.
    Notes: Abstract Several new benzopyran and benzopyranopyridine derivatives were synthesized via condensation of 2-amino-1,1,3-tricyanopropene (1) and diethyl 2-amino-1-cyanopropene-1,3-dicarboxylate (2) with salicylaldehyde and treatment of the resulted products with active methylene regents. The spectroscopic data of the synthesized compounds are reported and discussed.
