fluorine-adjacent site. It proved indeed possible to secure the desired regioflexibility in either way by relying on an appropriate substrate-reagent matching. This demonstrates once more the potential of the organometallic approach to diversity-oriented synthesis. [on SciFinder (R)]

nucleophilic ortho-mono-substitution of fluorine atom with magnesium methoxide. We have managed to increase the yield of targeted polyfluorosalicylic acids from good to quantitative. We have studied the tuberculostatic activity of polyfluorosalicylic acids. It has been found that minimum inhibitory concentration (MIC) of compounds is from 0.7 to 6.5 μg/mL depending on the structure.

Polyfluorinated analogues of salicylamide and p-aminosalicylic acid have been synthesized based on methyl polyfluorosalicylates. Polyfluorosalicylamides were obtained by the reaction with aqueous ammonia, while 4-aminopolyfluorosalicylic acids were prepared in two steps via regio-oriented nucleophilic replacement of para-positioned fluorine atom with azidogroup followed by its reduction. 3,4,5-Trifluorosalicylamide
heteroligand metalcomplexes based on polyfluorosalicyic acids and bipyridine-type coligands. In the heteroligand complexes, it was possible to achieve different ratios of polyfluorosalicylate and coligand, depending on the metal cation. The antimycotic and antibacterial activities of polyfluorosalicylic acids were studied and their metalcomplexes were investigated. The metal heteroligand complexes were found
Promising Antifungal and Antibacterial Agents Based on 5‐Aryl‐2,2′‐bipyridines and Their Heteroligand Salicylate Metal Complexes: Synthesis, Bioevaluation, Molecular Docking
challenge: A series of new 5-aryl-2,2′-bipyridines and their (polyfluoro)salicylatemetalcomplexes was synthesized. Their antimicrobial activity was evaluated in vitro against eight strains of dermatophytes, seven strains of Candida yeasts, eight strains of Gram-positive and two strains of Gram-negative bacteria. Using moleculardocking, we proposed that anti-staphylococcal action proceeds through the inhibition
