| titleOfInvention | Method for catalyzing synthesis of 4,6-diarylpyrimidin-2(1H)-one derivatives by sulfonic acid functionalized chitosan |
| abstract | The invention belongs to the technical field of green organic chemistry, in particular to a method for catalyzing the synthesis of pyrimidone compounds by sulfonic acid-functionalized chitosan modified by natural macromolecules. Aromatic aldehydes, aromatic ketones, urea and sulfonic acid functionalized chitosan catalysts were added to the flask, and the reaction was heated at 90°C under solvent-free conditions, and the obtained crude product was recrystallized to obtain 4,6-diarylpyrimidine- Pure 2( 1H )-ketone derivative. The invention has the advantages of good catalyst biocompatibility, high catalytic activity, easy separation and recycling, environmental friendliness and the like, and shows broad development prospects in the field of organic synthesis and catalysis. |
