Preparation method of 1,8-disubstituted naphthalene series polycyclic aromatic hydrocarbon mononitration derivative

The invention provides a preparation method of 1,8-disubstituted naphthalene series polycyclic aromatic hydrocarbon mononitration derivative. The preparation method is characterized by comprising thefollowing steps: S1, dissolving 1,8-disubstituted naphthalene series polycyclic aromatic hydrocarbon and subgroup metal nitrate in an organic solvent, performing a nitration reaction under 10-60 DEG Cfor 4-10 h, and then monitoring by TLC (Thin layer chromatography) till a raw material point disappears to finish the reaction; S2, cooling a product obtained in S1 to room temperature, performing suction filtration, washing filter cake with 5-10 mL of H2O and anhydrous C2H5OH separately, and performing vacuum drying to obtain the 1,8-disubstituted naphthalene series polycyclic aromatic hydrocarbon mononitration derivative. According to the preparation method of the 1,8-disubstituted naphthalene series polycyclic aromatic hydrocarbon mononitration derivative, the product yield is 93%-96%; theproduct purity is 98%-99.5%; compared with the prior art, the preparation method has the characteristics of high product yield, high purity, low cost and simple process, and is easy to industrialize.

PARTICIPATION OF PERI-HYDROXYL GROUP IN THE TRIFLUOROACETOLYSIS OF NAPHTHALENESULFONAMIDES

Trifluoroacetolysis of N-alkyl-8-hydroxy-naphthalenesulfonamides generally leads to the corresponding amines and naphthosultones.A model experiment shows that this reaction may be used in a two-step cleavage of sulfonamide protecting groups.
