2-(1-Hydroxyalkyl)azetidines react with bis(trichloromethyl) carbonate (BTC) after basic treatment to afford 4-(2-chloroethyl)oxazolidinones. The scope of this rearrangement was examined in detail and its efficiency was shown to depend on the class of the reacting alcohol and on the substitution pattern on the azetidine ring.
2-(1-羟基烷基)氮杂环丁烷在碱处理后与双(三氯甲基)碳酸酯(BTC)反应,得到4-(2-氯乙基)恶唑烷酮。详细检查了这种重排的范围,并且显示其效率取决于反应醇的类别和氮杂环丁烷环上的取代模式。
