The origin of good chemical and configurational stability of aziridine ester anions derived from (R)-(−)-phenylglycinol has been investigated. Kinetic acidity seems to play an important role in the deprotonation step and chemical stability of the anionic species. Spectroscopic investigations showed that the good overall retention of configuration was governed by the directing effect of the nitrogen
已经研究了衍生自 (R)-(-)-苯基甘氨醇的氮丙啶酯阴离子的良好化学和构型稳定性的起源。动力学酸度似乎在阴离子物质的去质子化步骤和化学稳定性中起重要作用。光谱研究表明,良好的整体构型保留受氮原子的导向作用控制,氮原子在烯醇中间体的烷基化步骤中充当立体中心。
