摘要:
Enantiomers of some new quinazoline derivatives bearing alpha-aminophosphonate moiety were separated under normal-phase conditions on two immobilized polysaccharide-based chiral stationary phases (Chiralpak IA and Chiralpak IC). The role of two chiral stationary phases (CSPs), polar modifier and column temperature on retention time and separation factor was studied. Apparent thermodynamic parameters were deduced from Van't Hoff plots and plausible mechanism of chiral recognition has been discussed. The semi-preparative separation of some compounds was executed successfully in n-hexanefisopropyl alcohol (IPA) on the Chiralpak IA column. The preliminary bioassay showed that both the enantiomers of the investigated series of compounds possessed similar anti-tobacco mosaic virus (TMV) activities. (C) 2009 Elsevier B.V.
