 Title    Cyclisierungen über Enamin-Zwischenstufen bei Amindehydrierungen Cyclizations via Enamine Intermediates with Amine Dehydrogenations  
 Abstract    The mercury-edta dehydrogenation of the 4'-aminosubstituted-acetophenones 1, 8a and 9a produced the ring cleavaged derivatives 7 ,11a and 12a, while the piperidine and its derivatives 10a -lOe gave rise to tetracyclic compounds 16a -16e and to methylenedi-enamines 19a -19d, the additionally C-l-fragment in 19a -19d probably coming from mercury edta. With addition of m-nitrobenzaldehyde to the mercury-edta dehydrogenation of substituted phenylpiperidines another route only generated the di-enamines 22. N Hg(ll)-EDTA r °) " -h2o \ a l N .
