Take a look at this Indole chemistry article:
“A Facile Preparation of 1-(6-Hydroxyindol-1-yl)-2,2-dimethylprop
Chem. Pharm. Bull., Vol. 51, 98-99 (2003)
Isn't even the title itself a contradiction? If there is a carbonyl carbon attached to the indole nitrogen, isn't that per definition an amide, rather than a ketone (as the nomenclature ...propan-1-one indicates)?
Also, look at the title in the top left corner of the HTML abstract page, is that a machine translation of the Japanese expression for "Detailed Table of content" perhaps?
