Shi, Yanyan published the artcilePreparation of a permethylated β-cyclodextrin chiral stationary phase by one-pot hydrosilylation and immobilization at the C2 position for chiral high-performance liquid chromatography, Application In Synthesis of 69097-99-0, the publication is Journal of Separation Science (2015), 38(21), 3669-3676, database is CAplus and MEDLINE.
A novel cyclodextrin intermediate, mono-2A-allylcarbamido-2A-deoxy-permethylated β-cyclodextrin, was synthesized by reacting allylamine and newly prepared mono-2A-azido-2A-deoxy-permethylated β-cyclodextrin by the Staudinger reaction and anchored onto porous silica beads by a 1-pot hydrosilylation and immobilization procedure to afford a novel chiral stationary phase. This stationary phase acts as a new member of the previous chiral stationary phase series immobilized on the cyclodextrin C2 position. This stationary phase depicted enantiomeric separation abilities toward bicyclic and tricyclic racemates under reversed-phase conditions. The resolutions for hesperetin and naringenin achieved on the current phase reached 3.91 and 1.11, resp., much higher than the previous permethylated β-cyclodextrin with the linkage at the C6 position.
