| titleOfInvention | Method for synthesizing diastereomer 2-imidazolone compound by silver and alkali concerted catalysis |
| abstract | The invention discloses a method for synthesizing diastereomer 2-imidazolone compounds by silver and alkali concerted catalysis, which takes a compound 1 and a compound 2 as raw materials, takes a monovalent silver compound as a catalyst, and synthesizes 2 by heating reaction in an organic solvent under inert atmosphere-imidazolinones; the chemical structural formula of the compound 1 is as follows: the compound 2 is ethyl isocyanoacetate, and the chemical structural formula is as follows: the chemical structural formula of the 2-imidazolinone compound is as follows: wherein Ar is 1 Selected from aryl, electron donating or electron withdrawing substituted aryl, electron donating or electron withdrawing heteroaryl; ar (Ar) 2 Selected from aryl, electron donating or electron withdrawing substituted aryl, electron donating or electron withdrawing heteroaryl. The invention can not only obtain the 2-imidazolone compound with high yield, but also easily obtain the diastereomer 2-imidazolone compound by adjusting the type of the added alkali. |
