2-oxazolidinones are prepared in stereomerically pure form from 3-hydroxy beta-lactams by a ring-opening-cyclization isomerization process. Application of this methodology to the total synthesis of the cytokinemodulator, (-)-cytoxazone, and its three stereoisomers is demonstrated. [reaction: see text].
