1,2,3‐Tricarbonyl Compounds, XII. Elucidation of the Constitution of the Reaction Products of Ninhydrin with 2‐Aminophenol and 2‐Aminothiophenol Ninhydrin ( 1 ) reacts with 2‐aminophenol ( 2 ) and 2‐aminothiophenol ( 6 ) to give products the constitutions of which were elucidated by means of the 1 H‐ and 13 C NMR spectra to be 10a‐hydroxy‐indeno[2,1‐ b ]benz[1,4]oxazine‐11(10a H )‐one ( 3 ) and 10a‐hydroxy‐indeno[2,1‐ b ]benz‐[1,4]thiazine‐11(10a H )‐one ( 7 ), respectively. Structures mentioned in the literature are on the one hand corrected and on the other hand doubtless established.
