The conversion of an aziridine to the corresponding oxazolidinone using only carbon dioxide and a catalytic amount of lithium iodide is discussed. In all cases, either no reaction occurred or a high yield of product was obtained. HMPA has been added to the reaction mixture, as needed, to drastically improve the regioselectivity. Net retention of stereochemistry between the starting aziridine and the
讨论了仅使用二氧化碳和催化量的碘化锂将氮丙啶转化为相应的恶唑烷酮。在所有情况下,要么没有反应发生,要么获得高产率的产物。HMPA已根据需要添加到反应混合物中,以大大提高区域选择性。观察到起始氮丙啶和产物恶唑烷酮之间的立体化学净保留。
