Saluting the sergeant: Phg‐BTA (see scheme) cooperatively self‐assembles into helical aggregates and shows unprecedented racemization behavior in the presence of base. In thermodynamically controlled conditions, the addition of a small amount of chiral auxiliary to this mixture results in a deracemization reaction and a final enantiomeric excess of 32 %. A theoretical model is presented to understand
向中士致敬:Phg-BTA(参见方案)协同自组装成螺旋状聚集体,并在存在碱的情况下显示出前所未有的消旋作用。在热力学控制的条件下,向该混合物中加入少量手性助剂会导致脱硝反应,最终对映体过量32%。提出了一个理论模型来详细了解所获得的结果。
