Resolution through revolution: It is possible to extract 3,5‐dinitrobenzoyl‐protected amino acids enantioselectively with the aid of a table‐top centrifugal contact separator and a catalytic amount of a chiral host compound based on the Cinchona alkaloids. Enantioselectivities of up to 80 % could be reached in a single pass. This allows the development of a process for the continuous separation of
通过旋转解决:借助台式离心接触分离器和催化量的基于金鸡纳生物碱的手性主体化合物,可以对映选择性地提取3,5-二硝基苯甲酰基保护的氨基酸。单次通过可以达到高达80%的对映选择性。这允许开发出连续分离外消旋物的方法。
