for the preparation of linezolid in particular, a more convergent and versatile synthesis was developed for the rapid preparation of numerous other oxazolidinone analogues. Toward this end, economical methods for the large-scale preparation of N-[(2S)-2-(acetyloxy)-3-chloropropyl]acetamide 3 and tert-butyl [(2S)-3-chloro-2-hydroxypropyl]carbamate 27 from commercially available (S)-epichlorohydrin via

We describe the highly selective copper-catalyzedUllmann-type coupling of bromoiodoarenes with oxazolidinones. 3,4,7,8-Tetramethyl-1,10-phenanthroline (Me4Phen) was identified as an optimal ligand promoting the desired C–N bondformation, while minimizing the competitive bromo–iodo exchange pathway that leads to formation of iodo-substituted and bis-coupled side products. The developed method is highly
Methods of synthesizing pharmacologically useful oxazolidinones are disclosed, and, in particular, a method of manufacturing a 5-(tert-butylcarbamoyl)-aminomethyl-oxazolidinone by condensing a carbamate with a tert-butylcarbamoyl protected derivative of glycidylamine or 3-amino-1-halopropanol.
