Redetermination of the crystal structure of the title compound, C3H5NO2, leads to a precise geometry for this molecule that is compared with the conformation of several aryl-substituted oxazolidinones. Molecular cohesion is stabilized by hydrogen bonds between the amine and carbonyl groups.

Due to the emergence of resistance to known antibiotics to various organisms, for example, Staphylococcus, Streptococcus, Enterococci, and Pseudomonas there is a renewed interest in the discovery of new antibacterials. Oxazolidinones, totally synthetic class of novel antibacterials, possess activity against drug-resistant Gram-positive pathogens ...

The need for effective antibiotics to manage the ever increasing frequency of antibiotic-resistant gram-positive infections in much of the developed world has led to the clinical development of the first oxazolidinone antibiotic, linezolid. Linezolid possesses bacteriostatic activity against both antibiotic-susceptible and resistant strains of ...

Oxazolidinones: New antibacterial agents
Trends in Microbiology, 1997The oxazolidinones are a new chemical class of synthetic antibacterial agents that are active orally or intravenously against multidrug-resistant Gram-positive bacteria. Their unique mechanism of action and activity against bacteria that pose therapeutic problems in hospital and community treatments make them promising candidates for antimicrobial ...

[reaction: see text] 3-Aryl-2-oxazolidinones are obtained in good yields through the palladium-catalyzed N-arylation of 2-oxazolidinones with aryl bromides. The nature of aryl bromides, phosphine ligands, bases, and solvents strongly affects the reaction outcome.

The structures of two substituted oxazolidinones, namely, 4-hydroxymethyl-4-methyloxazolidin-2-one [C5H9NO3, (1)] and 4-ethyl-4-hydroxymethyloxazolidin-2-one [C6H11NO3, (2)], are reported. Bond distances in the two structures are almost identical. The oxazolidinone rings both adopt envelope conformations; the fold in (1) is significantly larger than ...
