An efficient synthesis of 5, 6-dimethoxy 1- and 2-naphthols via Teuber reaction

Based on the oxidation of 1, 5-naphthalenediol (4) and 6-bromo-2-naphthol (9) via Teuber reaction, an efficient synthesis of 5, 6-dimethoxy-1-naphthol (1) and 5, 6-dimethoxy-2-naphthol (2) was achieved with high overall yield (16% for 1 and 25% for 2). The key steps of the synthetic strategy involved the oxidation of naphthols (4 and 9) to the corresponding naphthoquinones (5 and 10) and the conversion of 5, 6-dimethoxy- 2-naphthaldehyde to 5, 6-dimethoxy-2-naphthol formate through Baeyer-Villiger oxidation-rearrangement.

Singlet Character of Coordinatively Bound Oxygen, II

The oxygenation of 1,5-dihydroxynaphthalene (1) and 2,6-di-t-butylphenol (4) with Co-salen as a catalyst has been examined.The activation of oxygen in these reactions is different.From reactions with specific quenchers and the measurement of ultraweak chemiluminescence it is concluded that, depending on the nature of the substrate, Co-salen activates oxygen in the singlet state or in the radical state.This behavior must be considered when cobalt complexes are investigated as model substances of enzymatic oxygenation reactions.
