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 cytokine modulator, (-)-cytoxazone, and its three stereoisomers is demonstrated. [reaction: see text].
首次描述了两种不同的抗生素构架(β-内酰胺类和2-恶唑烷酮)之间的合成相关性。在这种方法中,通过开环-环化异构化方法,由3-羟基β-内酰胺以立体异构纯的形式制备2-恶唑烷酮。证明了该方法在细胞因子调节剂(-)-cytoxazone及其三种立体异构体的总合成中的应用。[反应:请参见文字]。
