| titleOfInvention | A green synthetic method for the synthesis of 1,2-benzothiazine derivatives by transition metal-catalyzed C-H activation/cyclization |
| abstract | The invention relates to a N 1 , N 3 -disubstituted imidazole-type ionic liquid as a solvent, NH-sulfenimide as a raw material, a diazo compound, an alkyne and a sulfur ylide as a coupling reagent, and a transition metal catalyzed C-H A new green synthesis method for the mild and efficient synthesis of 1,2‑benzothiazine derivatives through activation/cyclization reactions. Compared with other technologies, the present invention has milder conditions, simple operation, safety, and environmental friendliness; high catalytic activity, high reaction yield, and wide application range of substrates; solvent and catalyst can be recycled, reducing reaction cost. |
