Summary

  1. 1.

    The acyl derivatives of anthra-1,3-oxazine (I) enter into the azo-coupling reaction with aromatic diazo compounds; here the diazo group enters in the p-position to the tertiary nitrogen atom of the anthra-1,3-oxazine.

  2. 2.

    The arylazoanthra-1,3-oxazines (II) by hydrolytic cleavage of the 1,3-oxazine ring and the action of air are converted to the arylazo derivatives of N-1-anthraquinonyl-δ-aminovaleraldehyde.
