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.

allowing the preparation of the corresponding Grignard reagents in good yields. Furthermore, the use of a cocktail of metallic salts (Mg, ZnCl2, LiCl) in the presence of C60 fullerene (3 mol %) allows preparation of some functionalized polyaromatic zinc reagents. The resulting organomagnesium and organozincreagents efficiently underwent reactions with electrophiles, such as an aldehyde, an acid chloride

Development of Ni-Et-Duphos-catalyzed 1,2-addition of arylboroxines to aromatic aldehydes is described. The dramatic effect of boron reagent and phosphine ligand is observed. This method with a phosphine ligand allows asymmetric arylation of aromatic aldehydes (up to 78% ee). (c) 2007 Elsevier Ltd. All rights reserved.
