Enantioseparation of Substituted 1, 3-Diazaspiro [4.5]Decan-4-Ones: HPLC Comparative Study on Different Polysaccharide Type Chiral Stationary Phases

Abstract Enantioseparation of substituted 1,3-diazaspiro[4.5]decan-4-ones (1-14) was achieved using different polysaccharide type chiral stationary phases (CSPs), namely, Chiralcel OJ, Chiralcel OD and Lux-Amylose-2 using different mobile phases which were either n-hexane/2-propanol or n-hexane/etha...

Description
Summary:Abstract Enantioseparation of substituted 1,3-diazaspiro[4.5]decan-4-ones (1-14) was achieved using different polysaccharide type chiral stationary phases (CSPs), namely, Chiralcel OJ, Chiralcel OD and Lux-Amylose-2 using different mobile phases which were either n-hexane/2-propanol or n-hexane/ethanol mixtures of various ratios (v/v) at flow rate 1 mL min−1. UV detection was carried out at 254 nm and temperature of 20°C. The retention behavior and selectivity of these CSPs were examined in isocratic normal phase high-performance liquid chromatography mode. The results revealed that the amylose CSP (Lux-Amylose-2) could separate almost all the compounds under investigation in contrast to cellulose CSPs (Chiracel OJ and Chiracel OD) which resolved fewer compounds.
