1‐(5‐Aryl‐[1,3,4]oxadiazol‐2‐ylmethyl)‐3‐(p‐methoxyphenyl)‐1H‐[1,8]naphthyridin‐2‐ones (5) were synthesized by the oxidative cyclization of [2‐oxo‐3‐(p‐methoxyphenyl)‐2H‐[1,8]naphthyridin‐1‐yl]acetic acid arylidene‐hydrazides (4) with alumina‐supported iodobenzene diacetate (IBD) in solvent‐free conditions under microwave irradiation. The products are obtained in good yields and in a state of high purity.

A simple and highly efficient procedure has been described for the synthesis of 1-aryl-4-[p-bromophenyl)-1,2, 4-triazolo[4,3-a][1,8]naphthyridines (8) by the oxidation of the corresponding aryl aldehyde 3-(p-bromophenyl)-1, 8-naphthyridin-2-ylhydrazones (7) with chloranil under microwave irradiation. The products are obtained in good yields and in a state of high purity.

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.
