Method for synthesizing thionaphthothiazolone compound under catalysis of copper

The invention discloses a method for synthesizing a thionaphthothiazolone compound under the catalysis of copper. The synthesis method comprises the following steps: adding an N-substituted-2-naphthylamine compound, potassium sulfide, elemental sulfur, a catalyst and dimethyl sulfoxide into a reaction tube, carrying out a stirring reaction at 120-150 DEG C, carryin gout cooling to room temperatureafter the reaction is finished, and carrying out separation and purification on a product to obtain the thionaphthothiazolone compound. According to the reaction, the N-substituted-2-naphthylamine compound is used as a substrate, dimethyl sulfoxide is used for providing a carbon source, potassium sulfide and elemental sulfur are used for providing a sulfur source, and the thionaphthothiazolone compound is synthesized under the catalysis of cuprous iodide. According to the invention, the reaction does not need any additive, the N-substituted-2-naphthylamine is adopted to replace o-halogen N-substituted-2-naphthylamine, and the use of CS2 and a complex sulfur source is avoided, so a direct, green, efficient and valuable approach is developed for the synthesis of thionaphthothiazolone compounds.

SYNTHESIS OF HETEROCYCLES : SYNTHESIS OF NAPHTHO-TRIAZOLOTRIAZEPINES

Some new fluorinated naphthothiazolotriazepines have been synthesized by condensation of 2-hydrazinonaphthothiazoles with 1,3-diketones.
