Design, Synthesis, and Applications of Chiral Stationary Phases
Chemists who are engaged in the synthesis of optically active compounds frequently encounter the problems of assaying enantiomeric purity, assigning absolute configuration, and preparatively obtaining optical isomers in high enantiomeric purity. An almost ideal solution to all these problems would …
