Three "dimeric" C(9)-carbamates of quinine (QN) and quinidine (QD), that is, QN-QN, QD-QD, and QN-QD (chemically prepared mixture of the two cinchona-derived subunits), separated by an ethylene spacer were synthesized and used as chiral selectors for HPLC and capillary electrophoresis (CE) for the resolution of chiral acids. The chiral recognition abilities of these dimers and of several physically prepared mixtures thereof were compared in order to estimate the contribution of every cinchona… Expand
