 Title    Untersuchung zur 6 -Hydroxyindol-Bildung bei der Nenitzescu-Reaktion, IV [1] Cyclisierung von N-(Chinonylalkyl)enaminon-Derivaten, II [2] Investigation on the F orm ation of 6 -F[ydroxyindole in the Nenitzescu Reaction, IV [1] Cyclization of N-(Quinonylalkyl)enam inone Derivatives, II [2]  
 Abstract    Quinonylmethylenaminones 5 and 6 are synthesized and cyclized to spiro com pounds 7 and 8. Quinonylpropylenaminone 15 is made in the same way. Cyclization in acetic acid yields qui-nolines 11 and 12, in trifluoroacetic acid/trifluoroacetic anhydrid diacylenamine 16 is ob­ tained. The product o f 15 in perchloric acid is benzazocine 20. The structure o f 20 is proven by X-ray analysis. The course o f the reaction is discussed.
