Synthesis and antifungal activity of aryl aldoxime ethers and esters
نویسندگان
چکیده
Several ether and ester derivatives of aryl aldoximes have been synthesized from the aryl aldehydes. Structures of all new products were established by spectral methods. Many of the obtained compounds showed higher activity against fungal pathogens Botrytis cinerea, Fusarium culmorum, Phytophthora cactorum, and Rhizoctonia solani than the reference substance chlorothalonil, reaching 100% inhibition rate at 200 mg/L concentration.

5- hydroxyisoquinoline undergoes a smooth reaction with alkyl propiolates in the presence of triphenylphosphine (15 mol%) to produce the corresponding (E)-alkyl 3-(isoquinolin-5-yloxy) acrylate in good yields. When the reaction was performed by 2-methyl 4-hydroxyquinoline and 3-nitro 4-hydroxypyridine, similar aryl vinyl ethers were obtained.

Introduction: Nowadays the drug resistance outbreak in fungi is considered a serious threat to the health of human societies. Oxadiazole derivatives that are high biologically applicable can be a good alternative to common anti-fungal drugs. The purpose of this study was to evaluate the anti-fungal properties of new derivatives synthesized of oxadiazole and compare them with common anti-fungal ...
