A series of new chiral roof shape amines have been prepared from anthracene involving simple chemical steps and enzymatic resolution of isomers. The amines were screened as chiral solvating agents for the discrimination of enantiomers of several α-functionalized acids by the 1H NMR analysis. The system can also be used to accurately measure enantiomeric excess of mandelic acid by 1H NMR analysis. The
已经从蒽制备了一系列新的手性屋顶形状的胺,涉及简单的化学步骤和异构体的酶促拆分。通过1 H NMR分析,筛选了胺作为手性溶剂,以区分几种α-官能化酸的对映异构体。该系统还可用于通过1 H NMR分析准确测量对映体过量的扁桃酸。屋顶形状的CSA能够检测各种光学活性酸的1 H,13 C,19 F和31 P的标准四个核的信号偏移。
