| Abstract: | This newly designed route assembled a pyrazole ring with an aldehydic functionality over another pyrazole moiety. Further, formyl group was exploited in different routes such as condensation reactions, imidazole and pyrimidone/thione synthesis. The present reactions were performed with glycine, a facile catalyst, and the results were compared well with those of conventional methods. |
