efficient chiral inversion as the key step is furnished via Boc-involved neighboring group participation mediated by thionyl chloride. This preparation has significant advantages over the previously reported methods with respect to simplicity, cost efficiency, yield, and purification procedure as well as industry reliability. GRAPHICAL ABSTRACT
摘要 描述了((S)-1-((R)-oxiran-2-yl)-2-苯基乙基)氨基甲酸叔丁酯的一种方便、高产的制备方法。作为关键步骤的有效手性反转是通过由亚硫酰氯介导的 Boc 参与的相邻基团参与提供的。这种制备方法在简单性、成本效率、产量和纯化程序以及工业可靠性方面比以前报道的方法具有显着优势。图形概要
