    Description / Table of Contents: Synthesis of Pyrimido[6,1-a]isoquinolines with FormaldehydeThe isoquinolin-1-ylidenacetonitrile derivative 1 reacts with formaldehyde and hydrazine, acylhydrazines or hydroxylamine to give the 3,3′-bi(pyrimidoisoquinoline) 5 and the 3-amino-and 3-hydroxypyrimido[6,1-a]isoquinolines 6 and 8, respectively. 8 was transformed into 12, 14, and 15 which are unsubstituted at N-3 and have various oxidation levels in the pyrimidine moiety.
    Notes: Aus dem Isochinolin-1-ylidenacetonitril 1 wurden mit Formaldehyd und Hydrazin, Acylhydrazinen oder Hydroxylamin das 3,3′-Bi(pyrimidoisochinolin) 5 bzw. die 3-Amino und 3-Hydroxypyrimido[6,1a]isochinolin-Derivate 6 und 8 dargestellt. 8 ließ sich in die an N-3 unsubstituierten Derivate 12, 14 und 15 überführen, die verschiedene Oxidationsgrade im Pyrimidinring aufweisen.
