The desired styrenes of formula are prepared from the appropriate substituted acetophenone. Asides bromo anilines react with formoxime. Obtained oximes undergo a cycloaddition with the styrenes and give isoxazolines. Compounds of formula (I) can then be prepared in a palladium catalyzed carbonylative amination reaction of the isoxazolines.

The invention also relates to the processes for the synthesis of novel compounds of formula I or their pharmaceutically acceptable analogs, tautomeric forms, stereoisomers, polymorphs, prodrugs, metabolites, salts or solvates thereof. The present invention also provides pharmaceutical compositions comprising novel compounds of formula I and methods of using them. The compounds of the present invention are useful as antimicrobial agents, effective against a number of aerobic and/or anaerobic Gram positive and/or Gram negative pathogens such as multi drug resistant species of Staphylococcus, Streptococcus, Enterococcus, Bacterioides, Clostridia, H. influenza, Moraxella , acid-fast organisms such as Mycobacterium tuberculosis as well as Linezolid resistant species of Staphylococcus and Enterococcus.
