Definitions

  • This invention describes isoxazoline derivatives which are effective as antibacterial agents.
  • the compounds of the invention are novel and distinct from all other oxazolidinones in that the usual oxazolidinone rings are replaced by an isoxazoline moiety. These compounds have antibacterial activity comparable to the corresponding oxazolidinones. They are effective against a number of human and veterinary pathogens, including gram-positive aerobic bacteria such as multiply- resistant staphylococci and streptococci, as well as anaerobic organisms such as bacteroides and clostridia species, and acid-fast organisms such as Mycobacterium tuberculosis and Mycobacterium a ⁇ ium.
  • R 96 is a) an aromatic moiety having 6 to 10 carbon atoms, b) a 5-, or 6-membered aromatic optionally benzo-fused heterocyclic moiety having one to three atoms selected from the group consisting of S, N, and O, wherein the substituents (a) and (b) which can in turn be substituted with one or three -N0 2 , CF 3 , halo, -CN, OH, phenyl, C ⁇ g alkyl, C 1 _ 5 alkoxy, or C 1 5 acyl,
  • C 2 _ 5 alkynyl refers to at least one triple bond alkynyl group having two to five, two to eight, or two to ten carbon atoms respectively such as, for example, ethynyl, propynyl, butynyl, pentynyl, pentdiynyl, hexynyl, hexdiynyl, heptynyl, heptdiynyl, octynyl, octdiynyl, octatriynyl, nonynyl, nonediynyl, nonatriynyl and their isomeric forms thereof.
  • the reaction is diluted with ethyl acetate (100 mL) and water (50 mL).
  • the organic phase is separated and the aqueous phase is extracted with methylene chloride (4X50 mL).
  • the organic extracts are combined, dried over sodium sulfate, concentrated in vacuo and chromatographed on silica gel (230-400 mesh, 100 mL), eluting with chloroform/methanol (98/2).
  • the compound of Example 1, Step 1 can be prepared enantiomerically pure by a procedure from Ukaji, Y.; Sada, K.; Inomata, K. Chem. Lett. 1993, pp 1847-1580.
  • the reaction is diluted with ethyl acetate (100 mL) and water (50 mL).
  • the organic phase is separated, extracted with water (5 X 50 mL), dried over sodium sulfate, concentrated in vacuo and chromatographed on silica gel (230-400 mesh, 100 mL), eluting with methylene chloride/methanol (99/1).
