| titleOfInvention | 2-aminobenzo [4, 5] thieno [3, 2-d ] thiazole, derivative and synthetic method thereof |
| abstract | The invention mainly relates to a technical scheme for realizing the high-efficiency green generation of 2-aminobenzo [4, 5] thieno [3, 2-d ] thiazole and derivatives thereof by oxime lipid compounds, isothiocyanate compounds and sulfur powder in one pot under the combined action of double alkali and dimethyl sulfoxide without transition metal catalysis. The method takes oxime ester, phenyl isothiocyanate and elemental sulfur as raw materials, carries out three-component cyclization reaction research under the promotion action of dibasic and dimethyl sulfoxide, and synthesizes benzothiophene polyheterocyclic derivatives through intermolecular cyclization under mild conditions. The method does not need transition metal catalysis, and provides a new path for synthesizing benzothiophene compounds. The method has the characteristics of simple reaction system, mild reaction conditions, less reaction equipment, simple and convenient experimental operation, moderate yield and the like. |
