SummarySix new quinine (QN) O9-hydrazide derivatives with different substituents have been synthesized and immobilized on porous silica gel for HPLC. The chiral resolving power of these anion-exchange-type chiral stationary phases (CSPs) has been investigated and compared with that of four carbamate QN derivatives with analogous substitution. The unsubstituted QN-hydrazide derivative was usually the best chiral selector of the hydrazide series. Among the substituted hydrazide derivatives the… Expand
