β-Chloroamine hydrochlorides, produced stereospecifically and regiospecifically from aziridines with anhydrous hydrogen chloride in ether, are condensed with sodium carbonate in dry DMSO to afford isomerically pure 2-oxazolidinones.
The invention relates to compounds and processes useful for the preparation of protease inhibitors, particularly serine protease inhibitors. The protease inhibitors are useful for treatment of HCV infections.
