以1-苯基丁烷-1,3-二酮与(1S,2S)-(−)-1,2-二氨基环己烷为原料，合成了一种新的四齿手性席夫碱配体C26H30N2O2。分子中的手性中心具有相同的S构型，因为绝对构型是由起始试剂(1S,2S)-(−)-1,2-二氨基己烷的构型决定的。环己烷环呈椅状构象，取代基在最稳定的构象（反式环己基）中呈平伏状。晶体结构由两个分子内O-H⋯N氢键和一个弱的C-H⋯π相互作用稳定。
A new tetradentate chiral Schiff base ligand, C26H30N2O2, has been synthesized by the reaction of 1-phenylbutane-1,3-dione with (1S,2S)-(−)-1,2-diaminocyclohexane. The chiral centers in the molecule have the same S configuration, since the absolute configuration was determined by that of the starting reagent (1S,2S)-(−)-1,2-diaminohexane. The cyclohexane ring is in a chair conformation, and the substituents are equatorial in the most stable conformation (trans-cyclohexyl). The crystal structure is stabilized by two intramolecular O—H⋯N hydrogen bonds and a weak C—H⋯π interaction.
