| titleOfInvention | A kind of preparation method of synthesizing 2,5-disubstituted oxazole compounds |
| abstract | The invention discloses a preparation method for synthesizing 2,5-disubstituted oxazole compounds. N-(propargyl) arylamide and aryl acid chloride are catalyzed by a ferric compound to catalyze a series reaction of cyclization coupling, A series of oxazole compounds were generated by one-step method with yields ranging from 83% to 95%. The method has simple operation, simple raw materials and reagents, and high reaction yield, avoids the disadvantages of the traditional method such as troublesome preparation of precursors, expensive catalysts and harsh conditions, easy separation and purification of products, and is suitable for various substituted oxazole compounds. |
