N2 - 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 -NH2) 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.
