The present invention includes processes for producing 5-hydroxymethyl substituted oxazolidinone alcohols (III) from carbamates (IIA) or a trifluoroacetamide (IIB) using a dihydroxy compound (I) or glycidol (IV) starting material and for the transformation of the hydroxymethyl substituted oxazolidinone alcohols (III) to the corresponding amino compounds, 5-aminomethyl substituted oxazolidinone amines (VII) which are acylated to form commercially useful antibacterial 5-acylamidomethyl substituted oxazolidinone (VIII).

Process to prepare oxazolidinones

Compounds useful in the preparation of pharmaceutical preparations for the treatment of microbial infection where such compounds are of structural Formula I ##STR1## or pharmaceutically acceptable salts thereof wherein: R.sup.1 is --CHO, --COCH.sub.3, --COCHCl.sub.2, --COCHF.sub.2, --CO.sub.2 CH.sub.3, --SO.sub.2 CH.sub.3, or --COCH.sub.2 OH; X.sup.1 and X.sup.2 are independently H, F, or Cl; and Q is a five membered ting heterocycle (azolyl ring) of the general form: ##STR2## wherein A, B, and C are independently oxygen (O), nitrogen (N), sulfur (S) or Carbon (C). In all cases, the piperazine nitrogen atom is attached at the carbon atom of the carbon-nitrogen double bond.

Azolyl piperazinyl phenyl oxazolidinone antimicrobials

The present invention provides for new 5-amidomethyl, .alpha.,.beta.-saturated and--unsaturated butyrolactone antibacterial agents of formula I ##STR1## characterized by 3-aryl substituents that include, for example, indolinyl and phenyl substituted with zero (0) to two(2) halogen atoms and substituted in the para position with, e.g., piperazinyl, thiomorpholinyl (and corresponding sulfoxide and sulfone), thiazolidinyl (and sulfoxide and sulfone), morpholinyl, azetidinyl, pyrrolidinyl, piperidinyl, pyrrolyl, azepinyl, troponyl, 3,7-diazabicyclo�3.3.0!octan-3-yl, bridged thiazinyl or bridged oxazinyl moieties. In those cases where a ring nitrogen is present, then this is substituted to form an amide, formamide, sulfonamide, urethane, or alkylated with a wide variety of moieties. These compounds are effective against a number of human and veterinary pathogens, including gram-positive aerobic bacteria such as multiply-resistant staphylococci, streptococci and enterococci, as well as anaerobic organisms such as Bacteroides spp. and Clostridia spp. species, and acid-fast organisms such as Mycobacterium tuberculosis, Mycobacterium avium and Mycobacterium spp., and in organisms such as Mycoplasma spp.
