A comparative study has been made of UV/V-spectra of substituted 3H-phenoxazin-3-ones and phenoxazines which are obtained on reduction. For the bathochromic shift of the longwave absorption band of the ommochromes and of some phenoxazinones on reduction the 2-amino-/2-hydroxy-/2-methoxy-1-acetyl-3H-phenoxazinon-(3)-structure isnecessary.
Formation of dihydrotriphenodioxazines and dihydroisotriphenodioxazines by acidic treatment of some substituted 3H-phenoxazin-3-ones; isolation and characterization. A new perspective in the chemistry of ommochromes
