Novel 2‐(substituted)‐5‐(1‐methyl‐1H‐indazol‐3‐yl)‐oxazoles (13) were synthesized in moderate yields, from 1‐methyl‐1H‐Indazole 3‐carboxylic acid (1), by converting it into a variety of amides (12) and further its heterocyclization. The structures of all the compounds have been elucidated on the basis of IR, 1H‐NMR, and HRMS.
Novel 1-methyl-2-(2-substituted-oxazol-4-yl)-1H-benzimidazole derivatives were obtained in good yields and purity by treating corresponding 2-benzimidazolyl esters with acetamide in the presence of BF 3 -etherate, a Lewis acid.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
