摘要:
Investigation on the Formation of 6‐Hydroxyindole in the Nenitzescu Reaction, I Nucleophilic Addition toN‐QuinonlyenaminonesN‐Quinonyl‐enaminone6is synthesized. Its transformation into 6‐hydroxyindole5fails. Thus, structure6is no intermediate in the formation of5from1and2. Nucleophilic attack of trifluoroacetate on enaminone6yields hydroquinone9a, which is hydrolysed to10a,b. The structures of9aand10a,bare proven spectroscopically and by oxidation of10bto11, being equilibrated with phenoxazine12. The latter is reduce
