Four novel chiral stationary phases, N-undecenoyl-L-valyl-S(or R)-a-phenylethylamide(CSP-S-1 or CSP-R-1), N-pentadecyl-L-valyl-S-a-phenylethylamide (CSP-S-2) and N-octadecyl-L-valyl-S-a-phenylethylamide(CSP-S-3) were synthesized by a simple new method. Some racemic a- and b-amino acids, a- and b-hydroxy acids and amines with asym. alkyl group were resolved. The enantioselectivity of CSP-S-1 is the best one for their sepns.
