The geometrical isomers of (±)-3-hydroxyretinals were synthesized and characterized. Subsequently, simultaneous separation of eight isomers of 2- and 3-hydroxyretinals by high-performance liquid chromatography (HPLC) was accomplished and, in addition, complete separation of eight syn-anti isomers of 3-hydroxyretinaloximes by HPLC was achieved. Under these analytical conditions, the chromophore of the fly (Drosphila melanogaster) visual pigment was identified as 11-cis-3-hydroxyretinal (10).
合成了(±)-3-羟基视黄醛的几何异构体并对其进行了表征。随后,通过高效液相色谱(HPLC)同时分离了8种2-和3-羟基视黄醛的异构体,并且实现了8种顺-反异构体3-羟基视黄醛肟的完全分离。在这些分析条件下,果蝇(黑腹果蝇)视色素的发色团被鉴定为11-顺式-3-羟基视黄醛(10)。
