Research on antibacterial and antifungal agents. 16. Synthesis and antifungal activities of 1-[α-(1-naphthyl)benzyl]imidazole derivatives and related 2-naphthyl isomers
摘要:
Some 1-arylmethylimidazoles bearing a naphthyl group at the a position of benzyl moiety have been synthesized and tested as antifungal agents against Candida albicans and Candida spp. Such derivatives resemble bifonazole and naftifine, two important antimycotic agents of clinical use. Various compounds were found highly active when tested against Candida strains in comparison with bifonazole, miconazole, clotrimazole and ketoconazole.
An efficient and simple palladium-catalyzed approach for the synthesis of aryl ketones from low-cost nitriles and arylhydrazines using molecular oxygen (O2) as sole oxidant via C–N bond cleavage is reported. Various aryl ketones were synthesized in moderate to good yields under mild conditions. A possible mechanism involving the PdII/Pd0 catalytic cycle process is depicted, and a cationic palladium

carbon. However, little side-chain anodic oxidation is observed under any conditions tried; the radical–cations of electron-rich substrates preferentially dimerise and a strongly electron-withdrawing substituent at the 6-position (EtOSO2) promotes nuclear substitution. In contrast, oxidation with DDQ in aqueous acetic acid gives efficient side-chain oxidation for electron rich substrates, consistent

A valuable method for the Pd‐catalyzed Suzuki–Miyaura cross‐coupling of arylboronicacids has been developed, using α‐iminonitriles to replace acylnitriles. The reaction proceeds through selective activation of the C–CNbond, and avoids the “decarbonylation” side reaction of acylnitriles after activation.
