Page/Page column 74, (2010/10/20)
The present invention relates to certain substituted phenyl oxazolidinones and to processes for the synthesis of the same. This invention also relates to pharmaceutical compositions containing the compounds of the present invention as antimicrobials. The compounds are useful antimicrobial agents, effective against a number of human and veterinary pathogens, including gram-positive aerobic bacteria, for example, multiple-resistant staphylococci, streptococci and enterococci as well as anaerobic organisms, for example, Bacterioides spp. and Clostridia spp. species, and acid fast organisms, for example, Mycobacterium tuberculosis, Mycobacterium avium and Mycobacterium spp.

(2-Cyanoaryl)arylacetonitriles are obtained by displacement of halogen of 2-halobenzonitriles with phenylacetonitrile anions.The method also applies to a number of heteroaromatics with ortho-situated halogen and cyano groups and to heteroarylacetonitrile anions.The anions were generated by using potassium tert-butoxide or potassium carbonate.Calculated electron densities of the electrophilic centers reflect the reactivity in the displacement reaction.The calculations indicate that the potassium ion complexes with the cyano group of the 2-halobenzonitriles in nonpolar solvents, thus promoting competitive addition of the anion to the cyano group.Carbanions derived from acids with pKa ca. 19-23 similarly displaced the halogen of 2-halobenzonitriles.
