Abstract
Abstract Deoxy nor herqueinone and atrovenetin have been shown to be identical. On the basis of spectral evidence these compounds, and related substances, have been characterised as substituted 9-hydroxyperinaphthenones. This conclusion has been confirmed by oxidative degradation to the appropriate naphthalic anhydrides as well as by further oxidation to nitrococussic acid. The constitution of an important oxidation product, C 15 H 14 O 9 N 2 , obtained by the action of nitric acid on atrovenetin has been established. On the basis of this and other evidence the constitutions of atrovenetin and certain of its transformation products have been elucidated.
