To develop more advanced binaphthol derived CSPs, two new 1,1-bi-2-naphthol derived chiral stationary phases (CSPs) (CSP 1 and CSP 2) were prepared by connecting with silica gel at a hydroxy (OH) group of binaphthol. Previously reported two 1,1'-binaphthyl-2,2'-diamine derived CSPs (CSP 3 and CSP 4) were also prepared to compare the role of their functional groups (-OH and -$NH_2$) with CSP 1 and CSP 2. Enantioseparation of randomly selected, 11 chiral compounds on these four CSPs was performed and the results compared to each other. 3,5-Dinitrobenzoyl (3,5-DNB) derivatives of each CSP showed better results than the others and binaphthyldiamine derived CSP showed slightly better than binaphthol derived one.
为了开发更先进的基于双萘酚的手性色谱固定相(CSPs),我们通过在双萘酚的羟基(OH)基团上连接硅胶,制备了两种新的1,1-bi-2-naphthol衍生手性色谱固定相(CSP 1和CSP 2)。我们还制备了先前报道的两种1,1'-双萘基-2,2'-二胺衍生的手性色谱固定相(CSP 3和CSP 4),以比较其功能基团(-OH和-NH₂)与CSP 1和CSP 2的作用。在这四种CSP上随机选择的11种手性化合物进行了对映体分离实验,并对结果进行了比较。每种CSP的3,5-二硝基苯甲酰衍生物的结果均优于其他类型,而双萘基二胺衍生的CSP表现略优于双萘酚衍生的CSP。
