High net enantiomeric excess was observed for crystal collections obtained by crystallization of the TFA salt of a configurationally stable yet racemic axially chiral amidoamine in EtOH solution with or without stirring (up to >99% ee at < or = 15% crystallization).
高对映体过量的晶体是通过在 EtOH 溶液中对构型稳定但外消旋的轴手性酰胺叔丁基亚磺酸盐进行结晶，无论是搅拌还是不搅拌（在结晶度达到 15%以下时，ee 值高达>99%）。
