  Regioselective Metalation of Fluoroanilines. An Application to the Synthesis of Fluorinated Oxazolidinone Antibacterial Agents

  摘要：

  The regioselective para lithiation of 3-fluoro- and 3,5-dinuoroaniline stabase derivatives is described. These intermediates were subjected to a reaction sequence involving (1) transmetalation with zinc chloride, (2) a palladium-catalyzed coupling reaction with various pyridyl bromides, and (3) removal of the stabase protecting group, to generate fluorinated 4-(pyridyl)anilines. These compounds are. key subunits for the synthesis of selected fluorinated oxazolidinone antibacterial agents. Representative applications of these intermediates to the synthesis of three potent oxazolidinone analogues are discussed. One facet of the described procedure involves a unique iodocyclocarbamation reaction featuring a pyridine additive.

  The present invention discloses novel substituted aryl- and heteroarylphenyloxazolidinones which are useful as anti-bacterial agents. More specifically, the substituted aryl- and heteroarylphenyloxazolidinones of the invention are characterized by oxazolidinones having an aryl or heteroaryl group at the p-position of the 3-phenyl ring and additional substitutions at the m-position(s) of the 3-phenyl ring. A compound representative of this new class of oxazolidinones is (.+-.)-5-(acetamidomethyl)-3-[4-(3-pyridyl)-3,5-difiuorophenyl]-2-oxazolid inone.

  (EN) The present invention discloses novel substituted aryl- and heteroarylphenyloxazolidinones which are useful as antibacterial agents. More specifically, the substituted aryl- and heteroarylphenyloxazolidinones of the invention are characterized by oxazolidinones having an aryl or heteroaryl group at the $i(p)-position of the 3-phenyl ring and additional substitutions at the $i(m)-position(s) of the 3-phenyl ring. A compound representative of this new class of oxazolidinones is (±)-5-(acetamidomethyl)-3-[4-(3-pyridyl)-3,5-difluorophenyl]-2-oxazolidinone.(FR) La présente invention se rapporte à de nouvelles aryl- et hétéroarylphényloxazolidinones substituées, pouvant être utilisées comme agents antibactériens. Plus particulièrement, les aryl- et hétéroarylphényloxazolidinones substituées de cette invention sont caractérisées par des oxazolidinones contenant un groupe aryle ou hétéroaryle au niveau de la position-$i(p) du cycle 3-phényle, ainsi que par des substitutions supplémentaires au niveau de la position-$i(m) du cycle 3-phényle. Un composé représentatif de cette nouvelle catégorie d'oxazolidinones est (±)-5-(acétamidométhyl)-3-[4-(3-pyridyl-3,5-difluorophényl]-2-oxalidinone.
