For the determination of absoluteconfiguration, we designed and synthesized some hydrazines as crystalline auxiliaries having a heavy atom, and found that 6-chloro-2,4-dinitrophenylhydrazine is a useful crystalline agent for chiral carbonyl compounds. The absoluteconfigurations of chiral hydrazones prepared from the hydrazine and chiral ketones were determined by X-ray crystallographic analysis.
