WebPhenylcarbamoylated β-CD: π-Acidic and π-basic chiral selectors for HPLC. Chun Lin, … WebJin et al. synthesized phenylcarbamoylated α, β and γ-cyclodextrin chiral stationary phases and it turns out that the above CSPs have better enantioselectivity towards β-blockers than native CDs. Wang et al. [ 42 , 68 ] prepared two CSPs by immobilization of phenylcarbamoylated β-CDs onto alkynyl modified silica via “click” chemistry ... tenno sho
