A novel and facile method of introducing 4-hydroxyl group into the aromatic ring of azabenzanthrone compounds was carded out by reacting azabenzanthrone compounds with hydrazine hydrate or hydroxylamine hydrochloride and sodium hydroxide in diethylene glycol(DEG) solvent.The mechanism of reaction may involve an amino intermediate and follow a hydroxyl substitution process.
- Azabenzaathrone,
- Hydroxylation,
- Hydrazine hydrate,
- Hydroxylamine hydrochloride,
- Sodium hydroxide
