The enantioselectivity of a chiral catalyst can be determined from its racemic form by mass spectrometric screening of a nonequal mixture of two mass-labeled quasienantiomeric substrates. The presented method opens up new possibilities for evaluating catalyst structures that are not readily available in enantiomerically pure form.
手性催化剂的对映选择性可以通过其外消旋形式通过质谱筛选两种质量标记的准对映体底物的不等量混合物来确定。所提出的方法为评估不易以对映体纯形式获得的催化剂结构开辟了新的可能性。
